To be fair, Ramble also has some limitations, so neither platform has "anything goes"?

From Ramble's rules: "some things are just plain illegal and the owners of this community do not wish to be held legally liable to those who misinterpret this website's accessibility via 'the dark net' meaning that it's some sort of unmoderated free-for-all".

Legality differs from country to country and in my country we have very strict laws for example against any form of discrimination, incitements to violence or crime, selling stolen goods, etc. So this does restrict many then fully participating on a "free for all platform". So every user does need to make a judgement call based on their own values and what their country's Constitution or laws state.

"Any form of censorship" in my view then includes the removal of such attempts to sell illegal goods, to someone discriminating against another based on age, gender, sexual preference, religion, political beliefs, etc. Censorship is just a loaded term for moderation. They are exactly the same thing based on rules that exist on a site or within a country.
