This is pure, unadulterated nonsense. Go there and make a post about increasing max block size, bitcoin cash, or any other obviously relevant topic that doesn't suit their narrative and see how long your comment lasts. Theymos was clear from the start that he was going to use heavy handed censorship to force their narrative to people new to bitcoin.

Their moderation logs also aren't open so they can hide what they actually do censor. They also reorganize threads that don't go their way by most controversial, so they can further hide anything that doesn't say what they want. Claiming there is no censorship on /r/bitcoin is absolutely absurd, and if you really don't think it is true then you need to educate yourself.
