While I was reading your post,Darkomen, I immediatly thought that this ally hunter, level 60 with pet-autoattack was in fact a farming Bot.
Observe him a little bit the next time you see him. Does his attack go:
Hunters Mark,send pet, autoshoot, loot, run around in circles, rinse and repeat?
There are so many of those annoying bot programs out there. Felwood,BurningSteppes,Tanaris....they seem to be everywhere.
Mainly hunters level 60 with crappy green BoE stuff, unnamed pets (Boar,Cat,Owl) killing 24h/24.

I managed to kill an ally bot (I am ally too) in felwood for more than 15 times- I banished his target, he did even not recognize that the target was immune and hit it for over 20 rebanishs.
So I feared his next target right into a large pack of satyrs and watched him runnig after it...he dit continue to auto-shot his target while 5 satyrs hit him to death.
He was back 5 or 10 minutes after this, and I refeared his target...I think his stuff got zero durability after some deaths.
Saw him back the next day, on the same spot, doing the same stuff..

I find that they are really annoying, when I tried to help out a friend for his Onyxiaquest chain, it took us about one hour to (find and) kill some elite dragonkins, the place was and is still infested with bots.
