Most people don't take Wesley very seriously, so I don't think they consider it a problem.
I'm not even sure why that rule is still there, because it never seems to be enforced, although on occasion I've seen troll threads deleted when the same person is making a ton of them at once.
I think once you ban someone for one thing it's a slippery slope, like if you ban someone for racism then other people will be like "Why not ban homophobia too? Or just insults in general?" and then before you know it we're like any other forum with Nazi moderation.
I think one of the requirements of using a site like this is taking everything you read/see with a grain of salt.
