Report hunter Dauthaskot: killing people from a bug zone

I want to repot this player: Dauthaskot.

He was up the mountain in a zone where no one can go (a friend of mine try and was impossible to go up there) and sending his pet to kill all the low players. Like 1 hour doing this… If it’s possible to do something to avoid this kind of situations I would appreciate it.

I have more photos but I can’t post them because I’m a new user.

Let me know if more info is needed.
Thanks in advance,

This maybe a safe spoting but he is not close to FP or villages. I think it should be fine.
