It's quite obvious the FF14 community has its bad apples. About as many as WoW tbh, I've had an equal number of bad and positive experiences with other players in both games, ff14's bad experiences just tend to be more passive aggressive and bottled up while WoW is open about it. In both games the number of decent players far outweighed the rude ones though. Nasty players are just more noticeable.
It's not that ff14 has a bad community, it's nice overall, but we do have our share of toxic individuals. There's no point in pretending we don't. Comments like "he shouldn't have streamed if he didn't want harassment" or "it's just his fans, can't be us" are part of the problem. It's a clear case of harassment, every individual taking part should be banned. If the GM's don't have the manpower, that's all the more worrying and means you can break the rules if you just form a large enough group.
