On the other hand, I do think often accounts can be linked by these sorts of transactions, but it's very difficult to tell the difference. We all know damn well that bounty abuse happens and that a lot of bounty hunters think no one is paying attention and that they won't get caught trying to cheat.
I totally agree with you. I think that there are even such farms in which it is impossible to track the links between the accounts, as they adapt very quickly and know well how they are being tracked.
