I think we should keep Qaridarium. I believe he's a nice guy whose ramblings just have to be taken with a grain of salt. After all, he keeps some interesting discussions going. Just don't take his posts too serious and try to look for some truths between the ramblings (they are there).
On the other hand, I think its a bad idea to start topics like these. It is just naming and shaming which is a bad thing I believe. Like said before, if you have problems with a certain user, send a personal message to the forum administrators. Starting a topic is certainly not the way to go.
