The forum's been up a day with no tech issues, and I've already had to pull out the ban-hammer.
So, here's the banning policy. I don't decide on banning anyone, the posters do.
First time, it's 2 days. Then 5, then permanently.
Now, in special cases, I'll restrict a certain user to the Bitch.Piss.Moan forum for the lulz.
Now play nice.
