When I had an issue with another member here, I was told that if an Admin stepped in, it would mean we would both be banned. That's both a good and a bad thing. It's good that the Admin is completely objective. It's bad because we lose people with whom we might personally enjoy chatting.
The reason the place turned into a zoo is that TVT is not monitored by mods, who would see when rules are broken and take care of the problem. The Admin will not read all posts to see who is the biggest troublemaker. As far as I can tell, he/she looks at the thread or post reported and makes the call based on those alone. I doubt that's going to change since it's an un-moderated forum. Also, if threads or posts are not reported, the Admin will not know they exist because they are not acting as a moderator, do not read the forums.
