The five star reviews are full of misinformation. There has been a massive wave of transmasc trans rights activists being marked as unsafe, and no, it's not because they're doing or saying anything transmisogynistic. These are simply people who are speaking out about the struggles trans men face, and/or simply existing as trans men. The only way you could interpret that as not being safe is if you think all trans men are unsafe, which, I'm sorry to say, is an anti-trans viewpoint. It seems the people currently running the database only care about cis women and binary trans women, and either don't care about or actively despise all other identities. As other reviews have noted, intersex people are also being hit particularly hard. It used to be at least usable, and on paper it would be nice to have an extension like this that actualy works, but as the devs have made it, it's doing more harm than good.

Made unusable due to the devs' own active transphobia and unwillingness to moderate their own tool. Mass-"anti-trans"-flagging people who are themselves vocally trans-positive is now common. Used to be a good tool, is now entirely worthless.

This extension is NOT SAFE for transmascs or intersex people, especially POC.

genuinely good extension that has had a smear campaign against it. primarily by those who would like to pretend that being transgender makes one immune to being transphobic when it's in the extension's guidelines to "not to treat people differently just because of their gender, age or orientation"

these people can fully believe that trans women can be transphobic because "transandrophobia". but cannot fathom that they themselves can platform transphobic ideals.

overall great extension, even if you're not trying to block transandrophobia truthers as it accurately hits radfems pretty well

This used to be really helpful, but it's taken a disappointing turn.

used to be really helpful but as of late im seeing clearly trans friendly blogs getting marked red! and its usually transmasc or intersex people too :( really disappointing to see that people like me are being erroneously marked

you can literally go look at the listed guidelines on the github and see that this extension officially supports use of 4chan diy-slur "theyfab" and twitter diy-slur "tenderqueer" because "they're used to call out problems in our community!"-- equating them to truscum and transmed, endonyms first adopted by the group they refer to and which also notably do not soft-misgender said groups or imply their genders themselves are morally suspect, and refusing to acknowledge that these terms are constantly used in bad faith against people who have not committed any real lateral transphobia and frankly often in openly transmedicalist ways!

on top of this, the extension is wildly susceptible to brigading or biased usage in ways that are often completely superfluous and sometimes not even explainable through subjective intracommunity discourse (do we REALLY need to mark joseph mccarthy of all people red?)

i've used this extension for something like seven years, i've spent time going through terf blogs to methodically mark every party in a reblog chain sometimes, it is genuinely hard to drop it when it HAS and sometimes still DOES serve an important purpose! there's the second star! but it's kind of hard to justify keeping it up when trying to use it for its primary personal utility for me (trying to inoculate my posts from circling among transphobes by playing blocking whack-a-mole) is throwing more false positives than actual transphobes

...

also the fact that e-harassment luminary requires hate is marked green. one simply has to laugh

exciting edit/update in re: the assertions that this extension is a bastion of pro-transfem rhetoric and everyone who has left a negative review must simply be a transmisogynist review bomber angry at being called out: copy and paste the following wacky characters into an "x.com, the everything app" tab and check out the color op's display name is written in!: "/FEMCELSEDUCER/status/1907378415889432763"

This extension claims to be trans-friendly, but in reality it is very transphobic. It specifically targets transmasculine and nonbinary people, and anyone who supports them.

There have been targeted hate campaigns against trans people, using this extension as their tool to do so. And when someone doesn't like a trans person, they mass-flag them as a means of social isolation and bullying, while mass-greening the transphobe to trick anyone on the outside looking in.

The developers are in support of the harassers because they do not value transmasculine or nonbinary people, and believe it is impossible for someone to be bigoted against those groups.

I highly recommend not using this extension. It is a tool for transphobes, bullying, and social control among individual groups.

Intra-community discourse has worsened targeting to the point of uselessness. Uninstalling.

Removed my review for saying the devs hate transgender men and this app has been misused to mark transgender men, nonbinary people, and intersex people as red (antitrans). I can pull reciepts. I'm not playing around anymore, I'll keep putting my review back, or pursue legal action. Not a joke. Imagine dividing the trans community by lumping us in with terfs solely because we're not letting angry trans women bully us for things the cis patriarchy is doing to ALL OF US. Hypocrites. Edit: Also, if a trans woman disagrees with how people are talking about trans men, they've also been marked red. so. Edit 2: and don't call me a man if this is screenshotted or god forbid reported. Not one. Not AFAB either. Try again!

I used to have this installed on all of my browsers, however recently I had to uninstall it because I've noticed an uptick in the intersex activists I've followed being marked red for the crime of..? Talking about how their experiences fall outside of the expected binary. The group targeting of people whos experiences fall outside of a specific framework sincerely horrifies me. It's really disappointing, because a year ago this app was genuinely rather helpful, but now it seems like it's just being used to cause further infighting in certain sects of the community.

I'm a trans woman, this add-on has been excellent at letting me know who's safe and who isn't. All the complaints about "false" markings, and yet I've never come across a false marking yet. This tool is primary a way of marking transmisogynists, and if you're marked red and/or mad about this extension... you need to take a deep reflection of yourself rather than continuing to show your hatred of women sharing their experiences and trying to stay safe. Thank you to the developers and to all my sisters!

I loved this for a long time, but frankly more and more the people I see appearing red are people I don't feel are justified for it. This extension amplifies the "us vs them" mentality that is currently splitting the trans community and it's getting out of hands.

I see genuinely good people, trans girls, getting marked red just because they have the very radical opinion that "hey maybe intersex people have their own struggles and we should leave them have a place to express it without giving them hate".

I also see intersex people, who root frequently FOR trans people (including trans woman) be red just because they talk about their struggle which are different than the ones of trans woman.

And finally, almost just being a trans masc gets you marked red. I don't really get it. I see trans guys just minding their own business, doing their own things, marked red. Very often.

This isn't what the extension should be used for.

the people complaining about "false flags" are simply mad they can't get away with transmisogyny on the basis of also being trans anymore.

A wonder extension! Never been wrong.

Like many of the other people in the reviews, I've noticed that there has been a huge surge of of people marked red falsely--almost all of them transmasculine in some fashion.

This addon has become completely useless. It'd need a complete wipe of the database and a team of people working to actually review flags before allowing them through to make it helpful again, which is an enormous commitment. I'm honestly shocked there wasn't already some sort of system in place to prevent this given how easy it'd be for something like a transphobic 4chan raid to completely throw it off if they found out about it. It's disappointing hateful subsets of the trans community seem to have gotten there first but it really should have been expected, operating on the faith system is incredibly reckless when it comes to the online safety of vulnerable communities.

Youse need to either commit to doing better, or honestly you need to remove the app. It's actively harmful.

It's very sad what this extension has become. It used to be helpful, but now it's being used as a weapon against certain trans people and it's impossible to tell whether a red link means an actual transphobe, or if it means a trans activist that whomever runs Shinigami Eyes - or the masses sending in reports - personally disagrees with on the details of that activism. Very disappointing things went this way. Uninstalling, of course.

In the beginning this seemed like a good idea with mostly only the community knowing about it but then terfs started using it to hunt down blogs and social media accounts, now all I see are people I know getting flagged despite their support for trans/LGBT people. Either it's terfs taking over the flagging system defeating the purpose of shinigami eyes or a change in the userbase on what they consider trans-friendly. I appreciate the help it gave in the beginning but won't be using it anymore

Unfortunately this is useless for filtering out terfs, because while it does an okay job at identifying obvious Anti-Trans people, it also marks TONS of clearly trans positive trans and intersex people as "Anti-Trans" for really ridiculous reasons.
Mostly it seems to target trans and intersex people that use contradictory labels (or seemingly contradictory labels) for themselves. I don't think it's a great idea to assume how someone thinks about trans people based on the words they use. Since terfs co-opt our terms ALL THE F-ing time.
At this point the extension is no longer a thing that keeps the trans community safe online, but instead a thing that divides us.

This extension used to be good, until it was abused to mark trans people of colour, transmascs, and intersex people as transphobic for no good reason

Nobody follows the guidelines. All it takes to get marked as trans-friendly is to say something like"trans people are okay" and to be marked anti-trans all you gotta do is piss off a specific group of people on tumblr. Used to be good but most of the time I ignore it because it's utterly useless. Besides, transphobes don't tend to hide anymore...
