What honest user is buying and selling to themselves? It would not effect them in any way and if it is such a non-problem why has it been legislated into law for just about any exchange that is in existence. You know them puny little things like the NY and London Stock Exchanges.. This coin shit is just like gambling it is always nice to know your about to sit down at a rigged table or the dice have been shaved/weighted.
My point was that I don't see it as dishonest... it's a tactic anyone can use if they like. IF you make a rule against it, ONLY the honest users will be bound by it.
What's your rational? Saying there's a law is no argument at all, there's a million stupid laws. I honestly don't get why you'd want to monkey with a free market by stacking on rules that you can't even enforce.
No doubt plenty around here like you that defend the indefensible.
