For the most part it has worked great, but recently on some tumblr pages everyone is marked on red, even people I know for a fact are trans or trans friendly. I repeat: this only happens on certain pages, not all, so I'm not at all sure if it's just the page's theme interacting poorly with the extension or what.

I am curious about how the data to mark people is verified, though; so far I've not run across inaccuracies but then most of the time I wouldn't know. I hope there is some verification process even if it sounds like a labour intensive process.
