I'm not sure that "liking" or "not liking" somebody is going to prevent a posting. From what I've read, everybody here has people who hate them on the forum. If that would prevent one from posting, this place might be a ghostown by now.
Ironically, somebody as "hated" as Legion has a thread dedicated to them that is lasting five pages. It seems that the "hated" people here are getting the best advertising and the largest post amounts made to them.
