You do realize that the head moderator of /r/bitcoin is theymos the same person who owns this forum right?
TBF, there is no censorship here. While no one can deny that the mods of /r/bitcoin do delete some stuff that doesn't fit their agenda. You can talk about BCH here (in the Altcoin Board, obviously), but not in that subreddit (because it's actually /r/bitcoin and not /r/bitcoincash).
So both bitcointalk and r/bitcoin is administrated by the same person but with entirely different agenda with those sites.
