No, the only reason there's so many perm bans is because we've been having some issues lately with bots. If you get banned here, you get three "warning" bans and a grace period before we perm ban you. And we're honestly pretty lenient with the bans unless you do some really retarded shit. You seem pretty down to earth, though, so I don't think that'll be a problem for you.
As for flaming... it happens. A lot.
