I don't think you understand that post. The mod is clearly implying that he doesn't want to ban Wesley because *technically* he's not breaking any rules.
When you consider that the admin of the site just made a thread calling England the worst country in the world, and also all the LGBT-related trolling that other people do and get away with, Wesley is only slightly more annoying.
If you can learn to not take him seriously he's not so bad. At least he's not making a new thread every 30 minutes now. And plus, banning him would set a really bad precedent that people can be banned for essentially just having unpopular opinions/beliefs.
