Sometimes the request for evidence is quick, most of the time it's not. I've waited almost 48 hours on evidence. Half the strategy to get someone banned is just throwing shit at the wall to see what sticks, free labor isn't exactly the best. I've seen some really stupid bans as I'm sure many of us have.
Also to anyone saying it's too much work, you ban by PID, just require new sign ups on the site to register their PID to their forum account and current members to add it. It shouldn't take but 60 seconds to do.
