Person keeps annoying me at FM Giants

[IzHaN80]

So, i been wanting to hit 60, and i stood upon the 2 giant spot that is underground the Giant Fort at FM. Been there literally for days, hours, and whenever somebody sees you in there, everybody is cool and chill and ask you how long you will be there. I've met amazing people, but i am having problems with this person in particular, idk what to do anymore. This person shows up, asks for CC, then says that we can't claim 2 mobs in an outdoor zone (even tho i do handle them both without issues at respawn time) then despite the fact i tell this person there were others before that didn't claim or jump into the camp, starts attacking the mob that "claimed" and in my defense, i will attack the mob and wont let this person XP and then says i am breaking the TOS and ima get reported, clearly, trying to push me out of this camp.... What can i do before i get crazy?
