So you are saying that we should unban hundreds of thousands of alts used by cheaters to cheat?
So people with 100+ alts don't need to continue buying alts but can reuse the ones they have?
So basically the effort made by everyone, moderators, the anti-cheat and the community would be for nothing.
I agree with
@Elivat when I say that it's a big step in the wrong direction.
Besides, when someone is wrongly banned, they (should if it isn't already being done) reverse the ban of everyone that was banned by that specific detection.
In your case, if you where banned a couple of years ago, you can try to reappeal your ban.
