I've been very critical of other posts and some forum users, but I've never been censored. People have been equally critical of some of my posts. You must have really gone overboard to get banned. There have been a lot of free-wheeling discussions on this board, but I haven't seen any thread get closed until it degenerated into name-calling. Even then, the name calling remained on the forum. The thread was simply closed. The moderators even allow repeated threads criticizing their sponsors.
If you repeatedly crossed the line, this forum is better off without you. Go start your own web page and insult people to your heart's content.
