I tried blocking all trolls and shills here, but found that had the annoying side effect of making it so I didn't see posts from the legit good posters if they were replying to one of the shills. So I would always see a thread that supposedly had like 30 comments on it, then I open it up and I see no comments. Sometimes even if a thread comment is started by a shill, good posts come after it. I'd have no way of knowing though if it was a good discussion or not, so it was annoying just having to wonder.
