Bliz confirmed that going into Cata zones is exploiting.

[Pyrolight]

We are aware that some players seem to be exploiting this area and are currently investigating the matter. All appropriate actions will be taken for such exploitation.

The zone is there, it isn't fully accessible as there are mechanics in place that should be removing you from the area. If you are circumventing those mechanics, you are exploiting.

Go in and explore? Sure if nothing happens

Go in and farm Cataclysm mats or mobs for level 80+ greens and blues? Oh they dont think so
