Well, if it makes you feel any better, I have been thumped several times by the Steam Forums. Not banned, just issued infractions for alleged “spam” posts like “Lol! pasta! LOL!” and “Perhaps it was a valve employee? Lol!” and other such harmless banter. Come to think of it, each time I was issued an infraction, it was over a post with “LOL” somewhere in it. hm, perhaps I just need to refrain from humor when posting there?
Anyway, there does seem to be a lot of temp banning going on around here for both serious and playful instances. So I wouldnt take it to heart. =D
