Basically Punisher made a series of trades with another user.
Net effect was he traded a late 2nd for a late 3rd.
If he was new, you could argue rookie mistake.
Either he's really struggling to grasp draft pick value within the game or it's a deliberate thing being done to goof around with the game.
Is he a cheat? No, I don't see it. No evidence of multiple accounts I can see, nor any consistent collusion with a group of managers.
Is it, as someone suggest, deliberately messing around in the game for lolz? Possibly.
Even when things are explained fairly simply, there's little evidence Punisher seems to get the issues. Without knowing his age or anything about him, it's difficult to say why he's acting as he does.
I'd say he's someone whose trades do need to be looked at. Maybe he needs someone diplomatic ( ie not me ) to maybe mentor him if he's legitimate. Maybe the game needs a mentoring system per se.
