I simply gave him a few guidelines and a free reign. I can't be reviewing every single decision he makes. I might as well do the job myself.
The guidelines were :
1) Remove graffiti and spam and ban the guilty party permanently.
2) Discourage the posting of rubbish or constant harassment by issuing temp bans of a few hours. I left it to him to decide what "rubbish" means and what constitutes "harassment".
When the mod issues a ban, the member will see the reason when they log on so they can modify their behavior once their ban of a few hours is over.
Does he have biases? I'm sure he does. We all do.
When I do nothing to control the forum, I get complaints. When I try to put a few controls in, nothing changes. I simply get complaints from a different bunch of people. You can't please everyone.
