@Ghost Minor quibble, when I have seen people go full out card carrying member of The White Knights of Whatever, it's rarely been in pages--because that wouldn't show off their knowledge and research and how they totally are doing it right and should get to dictate how others should play things. It's always channel conversations. Pub or the equivalent usually. Does this happen in pages or skype or whatever, I'm sure. I don't join off site game groups for that reason, while I am happy to be there for friends, I have enough on my plate RL and otherwise than to have to deal with a circling the toilet bowl of negativity parade that those 'venting spaces' tend to devolve into.
I am not sure why MSB does not trigger the same kind of depression (though certainly it has and does, /especially/ some of the harder discussions we have had as a group about blindness to sexism/racism/homophobia) as a real time or coming into a group with 100s of messages. I can't even personally keep up with just general chatty positive discord or skype channels, except for my family one, so I just don't do 'em. I'm a little in awe of people who can maintain/keep up.
ETA: Nah, I don't have a problem on a game when someone is being an asshole to someone on chan, with asking them to stop behaving that way. I always appreciate it when others do the same as well. I usually do that before sending in a complaint, if it's bad enough, asking staff to please take a look at X channel around Y time, because this player is being very aggressively assholish and not really seeming to be willing or able to look at why people are getting upset. I don't think it's fair to send in a complaint without asking someone to stop, unless it's a safety thing or like--instant-nuke levels of egregious (in which case I think one should just take it to staff without trying to get involved in back and forth with that person).
