This used to be really useful for weeding out terfs and their alt accounts, but now it's marked a ton of trans people and intersex people as terfs because a white trans woman got mad at them. Unfortunately, I can no longer recommend this extention

Shinigami Eyes was great in the beginning. But transphoobic activists have basically destroyed its fundamental usability. Accounts from intersex people are almost all marked red, trans men too, random trans friendly blogs too. On the other side, so many unapoligetic transphobic accounts are marked green, which makes this addon less than useless. It actively damages the community as long as there are people hoping for actual indicators.

This add on has been wrongfully targetting trans men and intersex people. Not recommended.

Used to be good, the mods have started marking anyone who talks about intersex oppression or the issues trans men and trans mascs face as transphobic so now it's pretty worthless

This is an important tool to have for the trans community, and that it's become a tool against that community and to promote bigotry and division is sickening. Hopefully a similar extension which doesn't aim to harm transmasculine, nonbinary, and intersex persons will arise to replace it soon enough. Do not use this.

More and more people are getting flagged for such transphobic views as "sometimes bad things happen to trans men" and "intersex people exist." It was already kind of shaky because it was focused on a very strict idea of transphobia (ie, someone could be openly misogynistic, anti-gay, etc, but if they hadn't specifically disparaged trans people, they were clear), but that definition has become so comically narrow as to defend only a very particular concept of trans woman.

Functions, but I question why people like Contrapoints are marked as trans-friendly when they spout transphobic abuse to anyone who isn't trans in the way they like.

EDIT: Now just a platform for people who are 'the wrong kind of trans' to be shut down. Do not recommend.
