Let me be very clear about one thing.
This plugin is no longer about trans safety. It’s run by white radqueers who weaponize identity to control the narrative. Their version of “protection” is exclusionary, and deeply racist.

These are the same people who tell trans men to detransition, harass intersex people. They've brought back slurs like “theyfab” and regurgitate 4chan-era “passoid” discourse from the sewers. They claim transmisogyny is theirs alone to suffer and gatekeep and they shut down anyone who won’t bow to their white-coded trauma pedestal.

It’s not a safety tool anymore.
It’s a litmus test, enforced by radfem-baeddel TERFs.

TL;DR:
Delete this plugin. It’s a bad-faith plugin, and is total garbage due to being poorly moderated by trans-exclusionary TERFS. This is no longer a tool for protecting trans people. This is a tool for fascist neo-liberals cosplaying as anarcholeftists in their mom's basement (and they kinda have the hots for her!)

Used to use this until I noticed it flagged one of my tranmasc friends as red, then I started seeing it flagging a lot of other trans men as red, along with a number of NB folk I follow. Found that to be pretty telling, and honestly pretty vile, ESPECIALLY in this day when all us queer folk are under threat. Solidarity forever.

I've used this add-on for years. I think it's great in theory. Unfortunately, I have seen a comical amount of Trans people marked red on places like bluesky, because they spoke up about transmedicalism and gatekeeping of nonbinary identities only to have some plugin users coordinate a mass marking that is opposite of their character. I can only assume as a user that the application is now compromised by bad actors. Until this is fixed, my review is: don't use this plugin, it is NOT reliable.

this used to be such a useful resource to find out if somebody was transphobic and then it all went down the gutter. Ive seen so many blogs run by transgender folk be marked red like what???

This app used to have ACTUAL moderation before but the sabotaging is ridiculous. Please do better.

Don't listen to the review bombers giving it one-stars: a group of spiteful people on tumblr are organizing to lower its score. Shinigami eyes is a great extension. The best thing about it is that it's open to the community- no individual person decides what's right or wrong. If you disagree with the way someone's been marked, you can correct it yourself. I like to treat it like a "heads up". If I see the red, I can look more closely at the source and decide for myself if I agree. If you're capable of critical thinking, you'll be fine. Its great to know other folks in the community are keeping at eye out.

i've used this extension for well over a decade and i really don't know what happened. it used to be useful, it really did, but now there's so much false flagging that it's basically meaningless. it's a shame how bad the moderation has gotten. i wish there was an extension like this that actually cared about people other than white perisex transfems, but if you don't happen to be part of that demographic or even if you are but like to advocate for other people's needs or issues, you and your mutuals will probably get marked red eventually. it's sad. transmascs and intersex people and especially people of color ily and you deserve better than this.

The extension was great, then recently a lot of trans-friendly accounts started coming up red. I don't know why and who is at fault and honestly don't have a reason nor energy to care. This is simply meant as a warning to not download, because it doesn't work the way it was supposed to.

This used to be an extremely useful add-on, and I used it for years. Not to be trusted blindly, of course, but it helped to have a marker to check someone out myself to make sure I wasn't taking someone at face value who was acting in bad faith. But recently the false flags have been increasingly numerous, and not in a way that could be explained by understandable accidents. About 80% of the accounts I have double checked recently (I did actually count) have been misflagged as transphobic when they are obviously and outspokenly trans friendly (friendly towards the entire trans community too, not just friendly for one group while still being hateful towards another part of the community). Moreover, every single one of the false flags I looked into myself were transmasc. I don't know if this is people coming from outside the community poisoning the well to make identifying transphobes impossible, or whether this is an(other) intra-community concerted bullying effort against other trans people whose experiences are not the same as theirs. But the end result is that the add-on is no longer usable. Sorry to see it go, but a "trans-friendly" add-on that is actively hostile to large part of the trans community is not, in fact, trans-friendly anymore. It's transphobic with exceptions.

used to be very helpful but it turned into a community infighting cudgel because people cant be adults for five minutes, rip

used to work really well, now randomly flags trans people and i'm not understanding why.

Shinigami was once instrumental to stay safe online, but in recent time it's become evident that the developer has a bias and is using this trusted addon to manipulate its users by wrongly marking (and thus silencing) trans-friendly people as who either are, or speak on issues relating to, transMASCULINE and intersex experiences as transphobic (red), even as their peers universally mark them as trans-safe (green). This addon is very clearly in favour of binary trans women specifically while critical of any other trans identity even if the person is trans safe. This is an egregious misuse of power and Shinigami Eyes can no longer be trusted as a result.

i have used this extension for years and it has been great. the last few years - and in particular, the last year or so - it has gotten progressively worse. transfem poc and intersex, nonbinary, or transmasc people being automatically flagged as anti-trans for talking about their own experiences is wild. what about that is anti-trans? this is a tool i hate to lose, but nearly every blog i have recently seen marked red was so obviously trans-friendly, i just can't trust this anymore.

actively used to mislabel transmasculine people who talk abt their experiences with transandrophobia, bigender folks and intersex activists as transphobic (this is encouraged by the creator), while many TERFs manage to get marked as safe.

Used to be a very useful extension to avoid covert TERFs but now half of queer or genderqueer users are red. It's definitely been taken over by some people with an agenda to target "bad" trans and queer people. Uninstalling.

A lot of the people complaining about false flags should try a vital first step: stop calling trans women TERFs. TERF doesn't mean "person I disagree with in trans discussions/online discourse". It means Radical feminists who don't want trans women to exist.

If you're calling trans women TERFs, you weren't false flagged. You are not safe for trans women. This extension marks users who are and aren't safe for trans women.

Maybe fix your hearts instead of leaving one star reviews.

I want to start this by saying this extension is really, really helpful. It has saved me from having to engage with TERFs and other bigots of the like numerous times, and works very well in that regard. I don't think it should be removed, but I do think better moderation would be useful. There are definitely some false-flagging issues, like some reviewers have mentioned. I am not an expert on what good moderation would entail, but some sort of thing where you need to actually give a reason for marking (both red and green) could be a decent start. And, overall, people have biases. Of course the markings are gonna maybe be a little false with moderation like this. Shinigami Eyes has a ton of potential, and is already really useful, it just needs some better moderation.

Used to be really useful for finding out transphobes and terfs, now it's used to mark people who aren't binary trans women red for things like "being inclusive" or "speaking about their intersex experience" or even "not wanting to be called a slur"

marks intersex people, regardless of posts, as transphobic. the second youre openly intersex you're marked red.

The latest database update marks every trans and queer person red, who isn't a binary trans women. Everyone from nonbinary people to neopronoun users to intersex people and transmasc people speaking about anything other than trans women's struggle is marked red.

If the maker of this extension still follows the project: It's time to delete this extension! It has completly been hijacked by TERFs and bigoted infighting and gives no actual indiacation of trans friendlyness anymore. The only thing I see people use this for anymore is harrass each other, either but false flagging or bullying people for their falsely flagged status. This thing is no longer a tool for trans safety, but for trans infighting and targeted harrassement.

The creators of this extension claim it was made to fight transmisogyny, but flag trans WOC when they call out racism and transmisogynoir in the community.

Additionally, those who discuss intersexism or exorsexism are also often needlessly flagged as red, including several intersex transfems I've been following for years.

One look at the social media of the creators shows that they only support a very, very limited portion of the trans community, and are actively bigoted towards everyone else.

At best this extension has become a tool for petty discourse, and is now next to useless for identifying actual transmisogynists or transphobes.
