Well the organised campaign of hatred have led people to commit suicide, yes.
I would have thought this would be huge news, but I have never seen this anywhere. Do you have any more info?
There was a suicide of a trans employee at Riot that some anti-GG people tried to link to #GamerGate. There were some troll comments made under the #GamerGate tag though. No media outlet that reported on it linked it to #GamerGate or to her working in the games industry. I know there were some people calling it a hoax elsewhere online in the trans community, but it was later confirmed to have occurred. It was very sad to see people with various agendas on "both sides" behave so poorly over that one, though most people either didn't comment or were expressing condolences. That's the only actual death I'm aware of ever being brought up in relation to it. Maybe someone knows of other incidents.
What the actual fuck.
If that's the same trans employee I'm thinking of, I found out just hours after she tweeted about it, I saw her suicide note on Facebook. Never had met her, never knew her name until 3 hours after she passed, yet I was crying all night about it. Tragic. :( I doubt it was because of GG, though that might have added stress on top of the already stressful life transwomen have to deal with not just in this industry but all industries.
