Anyone ever been suspended for.....

[keyz77]

So there I was In Blackburrow last night, bored as a level 26 bard I was pulling mobs up top and casting Mez on them to allow players to kill them,
a bunch of the solo players started a party and so I kept pulling them,
then all of a sudden I drop and when I try to log back in....
Your account has been suspended?

No GM came and told me to stop, let alone did I think I was doing anything wrong?
I've heard of players getting paid (PP) to do this for players, I myself have been in the Warrens where high level players pull almost the entire zone for faction gains.
I'm confused as to why this happened and as to why I was not given a reason?
I have left a petition but there is no response.
