The OP shows up as a guest now so they must have deleted their account. I'm sure this is what CR envisioned with implementing the karma system........
CR did not delete him, I rather ebjoyed his posts. I checked the log, he deleted his account)
Bans get issued for spammers, and for making unacceptable comments about other members. If a member has been making reasonable posts, I usually just remove a post that is out of bounds, but I also issue warnings, 10 day bans, and complete bans.
Right now, we have had more trolls than usual that apparently just signed up to make stupid comments, they might be banned immediately. This sometimes quickly spreads to a flame war. Don't respond to a stupid post by calling the poster names, I know its hard, but I can cause things to get out of control quickly, thats why lots of deleted threads and posts happen.
