I didn't do anything, so I guess that it was just the same person.
You should check the ones found for alts. I'm sure there's many more we missed or got away. I'm not sure if they would have all belonged to the same person though because there was a lot found with no obvious patterns in sign-up dates etc. Maybe the way to cheat was published in some sort of bounty hunter telegram group or whatever and once people were getting caught for it that was publicised and everyone stopped. We know there are private telegram groups for bounty hunters where they share tips etc so it wouldn't surprise me. There's far too many people coming here to solely copy and paste straightaway and I get the feeling they're being told or advised to do that from somewhere. Something tells me they're all not just using their own initiative on that.
