If I could give 0 stars I would. This app inaccurately marks transgender people as transphobic and TERFS/conservatives as trans-friendly. People of color, intersex individuals, and transgender individuals who don't fit nicely into the boy/girl binary (xenogenders, nonbinary folks, etc.) are mismarked more often. Binary transgender people (transwomen and transmen) who speak up publicly about abuse or discrimination that they suffer are also mismarked more. Basically, it does the opposite of what it claims. This app will intentionally mislead you about the views of other people.

The only nice thing I can say about Shinigami Eyes is, "At least it didn't install malware onto my computer."

This add on discriminates against intersex and half of the trans community which is the antithesis of its stated goal.
For instance there's a noticeable portion of flagged blogs on Tumblr that have a had to make a pinned post clarifying that, no they aren't a terf, they're trans men and/or intersex. That is grounds for alienation as far as the creator of this extension is concerned. Either you stand with every queer person or you are against every queer person, this author fails to grasp that simple concept.
You have to make your own decisions, you have to pay attention, you can't trust the color of a hyperlink to hold your hand and tell you who is safe and who isn't.

intersexist as all hell

I know that queer people can still be transmisogynistic, and many of them are and deserve to be marked red. However, trans men, nonbinary people, and intersex people keep getting marked red left and right just for talking about their own experiences, even if they actively support trans women. This extension is not good anymore.

This add-on *used* to be super helpful. But recently the developers have decided to start wrongfully flagging trans masculine people and generally queer people of color red. Absolutely useless to normal people now.

Being used to falsely flag trans and intersex people. If you see a name in red half the time it's because the creator of the add-on purposefully misflagged them

currently being misused to flag trans masc., intersex, and trans poc as transphobic.

No longer useable as over half of the red accounts, on a manual check, are trans friendly/actually transgender. Attempting to rectify this isnt affective. It is much better to use your own judgement.

Absolutely unusable now.

serious racism problem - for some reason a lot of black trans folk and black trans-positive folk get marked red for calling out racism. meanwhile users who claim that being nonbinary is fake, suicide-bait trans women, and state that transmascs should detransition or die are marked as green.

i kinda doubt anything will be done about this. people just dont seem to care about racism and just focus on punishing people for calling it out. i have no doubt in my mind that the creator of this extension is either anti-black themself, or simply permits anti-blackness because it does not impact them personally

used to be useful but over the years a bunch of queer infighting has lead to a lot of trans-friendly spaces and people getting marked red because they're not trans in the "right way" or something.

While it was never 100% accurate, the current state of the extension is pretty dire. I appreciate that it can be logistically difficult or even impossible to manually verify every report, as well as emotionally draining, but letting it remain in this a confusing and potentially defamatory state is worse than it not existing at all. The young trans people I support in a queer youth group are pessimistic enough about life already without being made to be paranoid about things they needn't be or tricked into viewing potentially traumatic content as a result of a poorly moderated extension.

Transphobes famously spend almost all of their free time trolling anything remotely related to being trans online, you cannot run something like this without having safeguards in place to prevent interfernece. I sympathise, but I think it's time to admit that it's become too big for you to manage and to retire the extension. It's kinder than allowing people to believe it will give them any kind of control over their online experience and being let down.

My experience is that almost every trans individual who is intersex, POC, and/or nonwhite and who speaks openly in favour of trans rights has been marked red in this app.

Abuse of the app is rampant and uncontrolled to a point that it feels it is by design. I'm really tired of seeing actual trans activists getting put in the same boat as JKR. It's demoralizing how much this app exacerbates intra-community tensions by allowing petty users to mark anybody whose vibes they just don't like as "anti-trans".

Used to be very helpful but is clearly being used to target people someone doesnt agree with. I say that as a transfem who is hating seeing it used against my trans siblings.

It's a good addon, but it would be really nice to see exactly why some accounts or websites are marked red, also gives people complaining about being marked red for anti-feminist sentiments less wiggle room.

in theory useful but the people who currently decide who is and is not "transphobic" for this addon are hateful people who want you to trust their information unquestioningly. there is no way to see why someone is marked red or green, and many outspoken transgender people and activists are marked red for no apparent reason. do not use this extension if you actually want to avoid transphobes
