Ultimately it's the determination of the game designer on whether its an exploit or not, not the players.
I will reserve my judgement to see what they do to players that are reported after the announcement.

In video games, an exploit is the use of a bug or glitches, game system, rates, hit boxes, speed or level design etc. by a player to their advantage in a manner not intended by the game's designers.
