I've had Shinigami Eyes for a while and it used to be very helpful, of course, until it wasn't.
Recently, the mods have been red flagging those who are intersex, transmasc, and nonbinary and flag those who speak about intersex issues.
As an extension claiming to help flag terf rhetoric, I think it's very antithetical to be flagging against those who you're supposed to protect.

This extension used to be really good until in-fighting discourse led people to false red-flag people in the community. Obscene to see my trans siblings marked red for being a variety of trans someone else didn't aprove of. Intersex people advocating for their rights are also being flagged red which is nonsensical. Seems like the dev isn't interested in fixing it so I'll be going without.

As so many other users have already noted, the accuracy of the labeling has taken an enormous nosedive lately. Users are getting marked anti-trans for being supportive of intersex, transmasc, and nonbinary issues, the latter of which directly contradicts the extension's own guidelines. I have used this extension for years and install it on every device that supports it; I have now removed it from everything. Whether the developer is blatantly ignoring the extension being abused through mass reporting, or it is a more deliberate pivot of their politics, this is unacceptable. The queer community must not pare off its most vulnerable in order to appease those who view us all as degenerates.

Claiming to be a pro-trans and pro-queer extension when you deliberately flag intersex, transmen and transmascs, butch lesbians, multigendered, and people of color for talking about their trans experiences is a fucking rancid direction for this extension to take. This used to be reliable extension, and yet nowadays more than half of the people that are marked red are my fellow trans and queer folks simply talking about their experiences, not the TERFs that want us dead.

Please, for your own sake, uninstall this extension. Completely pointless. Trans Inclusive Radical Feminism still makes you a radfem, a cop, and a bastard. Queer liberation doesn't start and end at your "acceptable" white trans women. What a disgusting betrayal of the community.

chill tf out about intersex people jfc

This app used to be good, until they started incorrectly flagging intersex supportive people as transphobic.

was a great extension till it began flagging intersex, trans man & nonbinary positive posts.

Used to be a good add-on, now it's garbage. Transmasc, enbies, intersex people, and PoC are constantly getting flagged red. Do Not Rely On this extension anymore.

Wolf in sheeps clothing. You can't be pro-LGBT and exclude transmasc/enbys. Do better

Turning against transmasc, intersex and nonbinary people isn't cool, uninstalled >:I

Used to be super good. Now its intersexist and just plain cruel to those the mods/developer don't think belong in the trans community.

This extention feels less than worthless to me now. Protect and care for all of our trans, non binary, and intersex community members or what is the point?

Really disappointed to see the direction this extension took. After many years of use it is hereby removed.

It has lived long enough to see itself become the villain.

This used to be a useful extension but it's no longer reliable. I see red accounts that are supportive of trans people all the time. Since it can no longer serve as a useful warning, I will no longer be using it.

I used it for a while but it seems like it's not very useful anymore. I noticed many accounts tagged as red were accounts that never mentioned transgender issues in their entire existance... Possibly mis-reported?

It doesn't seem like this add-on has very good moderation, but again this might just be a mistake.

It used to be a useful tool to flag terfs and other transphobes, but lately the moderators have been just flagging a bunch of intersex people and trans men... Completely useless now. If you see someone marked red 9 times out of 10 they're intersex or transmasc.

its become beyond useless... lately im seeing way too many trolls marked green

This extension used to be helpful, but now transmasc, intersex people, and their allies are being falsely labeled as trans-unfriendly. Heartbreaking, really.

This addon is being actively used to target transmasc people online. There are a significant number of transphobic people marked safe because their transphobia is "acceptable" to the creators of this addon and a significant number of people incorrectly marked as unsafe because they support trans people the creators of this addon don't like. Used to appreciate this app, but it's now just being used for lateral violence.

As of recently, it's become very unreliable. Like other people are mentioning here, people are being marked as red that really shouldn't be, like folks who talk about issues that intersex and transmasculine people face. :(

I love the concept of this extension and have been using this extension for years now, but it has become extremely unreliable nowadays with the creator's own prejudices affecting moderation. Lots of people are being falsely flagged as transphobic just for being supportive of intersex folk and sometimes for no reason at all so I would recommend steering clear of this one.
