There is censorship there. There are autobots that delete shit all the time for reasons unknown to the mods.

Reddit is controlled opposition. You must allow and even encourage both sides to talk (at least until control is complete). When there are two sides, each looking at the other, it creates division and cognitive dissonance in the larger population. You don't need to censor all that much to keep the eyes off the ones who are really in charge. Controlled opposition is the method by which you keep all eyes off the real players. Hint: the real players are not the CEO's of Blackrock, or Citadel, nor any other company or "billionaire" mentioned on r/Superstonk.

Not to say that reddit isn't currently white hat controlled, it may be, but there is still censorship and banning occurring, so I don't know. It is still a battlefield.
