It isn't. Exploit =/= Cheat
Exploit = discovering an aspect of the game that is advantageous to the player, and using it. No codes/cheating devices/hack/outside programs required. In other words, not the player's fault the developer left the door wide open.
Yeah, it doesn't work like that. Never has, never will.
The thousands of people that exploited the pre-patch slicing didn't get a warning or got banned.
(I assume this is true, as nobody in the TOR OT has said anything nor have I received one.)
So maybe there is a difference between exploiting a game mechanic like slicing and purposefully flipping zones to generate money which is only possible by not attacking members of the opposite faction.
You're blind if you can't see the difference. Slicing was just set too high. Players weren't exploiting anything because they were just pushing a button. This is like saying players are using an exploit because a developer made a class too powerful or something.
