How is cheating possible?

[Boron]

Anyway, Im opposed to cheating, yet I do believe you can change your cheaty ways.
When I was younger I cheated all the time (and never played MP) but after I grew a bit older I realized (with help from my brother) that cheating isnt fun, and Im cheat-free-clean ever since (unless in very specific games under very specific conditions, only SP, only FPS games and only after I finished the game atleast once).

that's exactly my viewpoint too . no cheating in mp .
i even don't cheat normally in sp only rarely for fun after i completed the game already or if a bug doesn't allow you to continue normal .
