And people's posting history stays with them. When someone's getting out of hand, I review their posting history before deciding how to deal with them. If they show a history of being a dick and trolling at every opportunity, they'll get a harsher reaction than if they just got wound about something specific. Alaric is a good example -- he kind of went off in that thread (I think it was that thread), but that's not normally him. So no biggie.
Some other people though (and not naming names) are showing signs of being on this forum just to get in fights. Sooner or later, the ban hammer will fall...
I told my kids, "Someday, you'll have kids of your own." One of them said, "So will you."
