Exploiting Bugs and Glitches in Beta.

Been a little debate about this in game but I wanted to know.

For those who intentionally exploit a bug such as Warlock Grimoire or Hunter Call Pet bug will there be any action taken against them?

I always thought you should follow the Rules just like you would have to on Live and would have the same action taken against you if you do exploit those.

I don't mean Permanent ban but lets say a Lock who everyday is coming to SW or Orgrimmar or some other Zone to just kill everyone he can, doesn't report the bug or anything about it just exploits it, would he have actions taken against him by Blizzard.

Just Curious.
