I do not recommend. It marks outright TERFs and radfems as green, and transmascs/men, nonbinary people, and intersex people as red.

used to be useful but turned into hot garbage recently. have seen straight up radfems, gendercrits, transphobes, etc marked green and transmasculine, nonbinary, and intersex people marked red for having the wrong discourse opinions lol.

This used to be an extension that did what it claimed to do, but now it marks transmen and mascs and intersex people as red (unsafe), while marking people who spew the most VILE hatred towards them as green (safe). Whoever mods the extension should be ashamed.

So cool that my friends are getting marked as transphobic because of petty discourse while openly transphobic accounts are out here being marked as trans friendly thank you!!!!

I'm a trans person who has been dedicating years of my time to making a website from scratch called thetransgenderdictionary.com where I compile resources and information for all trans and trans-adjacent people and this extension marked it as transphobic lol this thing is a joke.

Transmasc/trans men, nonbinary, and intersex users discussing oppression *without* mentioning or blaming trans women are regularly marked red, as are transfems/trans women who are even vaguely associated with them (one prominent Tumblr user was marked red for a post arguing that hatred of men/masculinity harmed transfems and only tangentially mentioned transmascs). This extension does the work of transphobic society itself in punishing trans people who dare to acknowledge the oppression they face when that oppression can't fit into a black-and-white binary.

Constantly see large profiles on social media joking about killing certain trans groups marked green and trans profiles talking about legislation and oppression marked red. Completely useless and has no way to counter mass false flags.

"Highlights transphobic/anti-LGBT and trans-friendly" more like only doesn't highlight trans women who are the "right" kind of trans women. Ironically this extension is INCREDIBLY transphobic and also homophobic. It's a scam, don't download.

Also, I don't see why you would download this in the first place. Why would you trust a Firefox extension to make choices for you about what to believe? You're just begging to get fed misinformation. Go through a page yourself and make your own informed conclusion instead of taking the easy way out.

Ya I uninstalled this after I realized it was completely useless for trans guys, and I'd constantly see people saying vile things about us with a cheerfully green username. Don't install this if you want any useful information as a transmasc.

Horrifically biased against trans men/mascs, nonbinary people and intersex people.

Not helpful at all. Completely biased against non-woman gender-queer people and intersex people. Pretty much useless and needs a whole lot of improvement.

Downloaded thinking it was useful but apparently it's biased against pretty much everyone who doesn't hate non-woman gender-queer people and intersex people???
Ehhhhhhh...

Wouldn't recommend using this extension anymore. In the past I've noticed radfem accounts exploiting the "peer-review" bit to get trans people mass-reported as anti-trans/red in an attempt to ostracize them from their own community, so I knew the extension wouldn't last long, but I never would've expected it to be taken over by those exact same people.

I've seen transmascs marked as anti-trans, intersex people marked as anti-trans, BLM supporters focusing on trans PoC - you guessed it - marked as anti-trans, meanwhile accounts who are literally infamous for mocking the suicide of Eden Knight are marked as green/pro-trans. Even people who frequently use the "TERFs please touch" tag on tumblr are green now.

I wondered WTF was going on so I did some research just to find out the extension is run now by gender-essentialist, transmasc-excluding radfems who will mark you as anti-trans if you so much as acknowledge that transmasc or intersex people face oppression, and from what I've heard the developers have openly defended this decision, leaving me to believe it's 100% intentional and not just poor moderation.

Shinigami Eye was never entirely reliable, because you shouldn't rely on a peer-view extension to tell you who does and doesn't hate trans people, but now it's become the opposite of what it was made for. Long story short: this app is useless now and I doubt I'll ever be using it again.
