the problem I have is with permabans unless is really homophobic, racist, threatening attitude.
the thing is that a lot depends on your subjective view of that poster.
If it concerns a poster many on MTF like, the reply to a ban will be one of "just an innocent joke, if yet not very tasteful but he didn't mean it that way, unban him".
Why should one poster get away with something because you like him when somebody else gets a ban for the same without protest.
I remember one of Mikey's bans for making xenophobic remarks against Spain/Spaniards. I also remember us giving him a bollocking over that because it may have been a joke to some but he was already walking on thin ice.
