Used to be useful. Infiltrated by TERFs, overrun with racism, exorsexism, and lateral transphobia. Cannot speak for other social media sites as I don't use them, but it's useless on tumblr. It used to be if I saw a red name and checked, nearly 100% of the time it was a TERF/radfem or otherwise transphobe. Now, if I see a red name, nearly 100% of the time it's just a trans masculine person or an intersex person. It seems like he/him in bio is enough to get you marked red on this extension now lmfao. Would not recommend, hope an alternative that seeks to protect ALL trans people is created.
