72 hour suspension for farming chests.

I was NOT aware that this was against the TOS. Can anyone please explain to me why stealth running dungeons is against the TOS? i have to go in there and do my best to kill things, im not using any kind of exploit (terrain is an example or bugging..)

i use only my abilities to kill the mobs. I spent alot of time gearing up this character, i find a half decent use for him finally and i get the shaft, no warning just straight out suspension.
