I do it just to see exactly what those silly, power-modding Moderators are up to. I often have no idea why, or can find no legitimate reason why the person was banned or suspended, only that they may have offended a certain moderator.
A lot of the people banned or suspended for their posts seem to be the victims of picky-choosy moderating. I read the posts and usually find nothing wrong with them - No violations of ToS or forum rules. From what I've seen, people are being banned or suspended for, in general, providing an honest opinion.
Not saying there aren't any douchebags out there or anything...
