He has mentioned this before, but so vaguely that I assumed he was exaggerating and just referring to the fact that everyone knows he's Hector Martin, and Luna DOXXED him.
However, he's given real details this time, and I'm pretty sure he's telling the truth. Sima is Simona Vetter (
Mastodon I'm sure he knows he looks atrocious now that he's trooned out and he's just coping about how it's a "running gag"), who seems to personally dislike Hector (
LKML post, I actually wasn't able to find the original posts from either Sima or Hector). Most likely, he really did reach out to the Freedesktop CoC committee complaining about Luna abusing him and DOXXING him, and they refused to ban Luna or call him out publicly. Hector probably has no knowledge of what actually happened behind closed doors, and is simply lying about Sima to get people to harass him (very stupid move), and most probably they simply already knew he was Hector, because it's an exaggeration to call it a secret, and they knew he was just doing DARVO shit. Of course, Hector is a tranny, so he would get favorable treatment, but so is Luna, so it cancels out.
