my thoughts: trolling seems to be more accepted more in the community threads, but only if you're a known member of that group. poligaf may be an exception to this, but only because the regulars there aim for a slightly higher level of discourse and loathe hit-and-run posters.
i rarely venture into the gaming section, but that does seem to be where most of the mass account suicides happen. something about the gamer demographic, subject matter, anonymity and god knows what else leads to some odd online behavior and modes of 'debate'. i am somewhat proud that the community-at-large didn't turn puerile and devolve down the evolutionary ladder in response to the Kickstarter on sexist videogame tropes.
