Bug abuser: SM PET attacker.

Server: West - Siel. Players: Aoiyoshii (SM) Anurhat (GLAD)
I'm not entirely sure if this is something i can report upon but a friend told me to post it in the forums if it keeps happening so here I am... Normally I don't really care much if someone attacks my pet randomly but this one guy was very persistent and kept following and attacking my pet.. After doing this once, i forgot about it. After seeing him again, he did the same thing and chased me again. thanks in advance, please see the images below inched:

• When he first starts attacking
  
• I told him that I'd make a report
  
• He still consistently follows me to kill my pet...

(I resized for the forum but if you need the full resolution for each let me know.)​
