Well, what he is doing is not really censorship, he believes xt is an altcoin therefore anyone who posts or talks about it in the bitcoin section will get removed. It happens already with any altcoin, if you start a discussion here about litecoin it will get removed because it is an altcoin. By your logic, any deleted post about any altcoin is censorship.
Forget it. Just one example: The second most viewed thread has not just been moved. It has been locked. You can't fool all the people all the times. The tide is turning.
