As Solari says, evidence will not EVER be provided in cases of multi-accounting. It should be plainly obvious why this is the case. We do not lock accounts on a whim, and prefer to leave questionable cases alone for future checking.
Investigating multi-accounting cases is a very time consuming, demoralizing, and thoroughly unenjoyable process. It chews up many hours of the time of several dev team members who could otherwise be improving the game.
If one of these people who gets locked for multi-accounting approaches you to protest their innocence, remember rule #1 of multi-accounting: Multis are liars.
