Is rigged CPQ2 an exploit?

no its not

off topic. Boo koopaforce. They kicked me out without any reason. One of the reasons I quit maple.

You quit because some unknown guild kicked you?

It depends on your definition of "exploit."
If you look at "exploit" as in abusing the system that was meant to be, then yes, it is an exploit, because although it is within the boundaries of the ToS, it is not morally sound.
If you look at "exploit" as in abusing the games mechanics in a way that cheats the system, then no, it is not an exploit because you are still playing the game within the confines of the ToS (to an extent, for some rig CPQ with multiple accounts all tied together).

I believe, correct me if I'm wrong, they're referring to having 2 parties enter CPQ, and have one just sit there while the other racks up points, automatically getting the win.
