The point I'm making is that all of those things can be proven false. I can log onto a "roleplaying mandatory" mud and start talking about how it's just a game, or log onto a "G rated" mud and start making sexual comments. All the admin can do is ban me after the fact, if they catch me. In that respect it's no different to players selling gear to each other.

The same is true of anything - but you can verify the existence of RMT. If someone says "This mud sold me a sword of uberslaying for $5", all they have to do to prove it is provide the receipt. That's much easier to verify than things like codebase, world size, originality, year created, etc.
