Kind of a slow creep rather than a single event, but I regularly played Red Orchestra 2 on a particular server for several years, often topping the score board and attempting to participate in the text chat at least, but no one ever acknowledged my existence in any way, and there were a lot of regulars in there who had formed their little clique. It was the kind of thing where someone would do something and the chat would explode with hahas or amazement or whatever, but nothing I ever did ever got any kind of response. Kind of got me out of attempting to engage with anyone online eventually. I just turn any chat there is in a game off these days.
The more traumatizing single events were just woman related shit
