Let me just point out:
Communism is not evil. Its an idea that makes evryone equal so no one can get super rich and no one should get super poor, yes it does differ to capitolist views on induviduality.
The main reason people envision communism as evil and wrong is because of dictators, E.G. Stalin and Castro. But the main reason for these views is propoganda from the US and NATO during the coldwar.
Newgrounds is not therefore communist, what you discribed is more of a dictatorship. Even then users get alot of freedom, or else why would thousands of people join as members?
