Actually. The site owners can. They can control the site content as much or as little as they want. You say it's a communistic society. It isn't. It's a dictatorship. Quite a bit different. They make the rules. The moderators do their best to enforce them.
They don't own AMS. They don't own Z1. AMS doesn't own 3ZC. Z1 doesn't own 3ZC. But when a site sponsor is accused of something without undeniable proof, what do you really think is going to happen?
