No evidence at all exists that Wu was ever actually dysphoric. Her transition began around 2005, when she began taking hormones, but there's no evidence one way or the other that she ever got her diagnosis. Unlike a lot of other lolcows, Wu's taken numerous steps to hide her records so evidence of her name change (which we got) is about as close as we're ever going to get, and we're unlikely to ever truly know for sure. General consensus amongst Kiwi Farms experts on Brianna Wu is that she got one but didn't really put much effort in.
The only reason that I (personally) have never given Wu shit over her gender beyond periodic needling is because she's at least made something distantly resembling an effort to pass. What we know for sure is that she's had considerable surgery, all of which has left visible scarring and is quite visible in certain lighting conditions.
Especially visible are a scar on her throat from a tracheal shave, scarring from Forehead Reduction surgery, and scaring on her legs consistent with SRS.
They do this by disallowing "random" email sources like Gmail, Hotmail, AOL, etc, but they aren't smart enough to pick up on a spoofed email address that's just a redirect to a different account, or an official-looking address that in actuality isn't.
That's a big reason they have an omnipresent group of trolls amongst them that get banned only to come right back within the span of an hour on a different account. Their much-vaunted security procedures do nothing to deter the determined shitlord.
