I have no doubt that censorship of TPP is being used on reddit to help pass it. The real question is how deep it goes. There are shills of all sorts of causes that brigade certain news/politics threads to make sure their agenda is known. There's something not right about this one though. This particular instance of censorship comes right after Pao's new rules, which makes me think that this censorship of TPP is actually being run by reddit and not just shills.
