So, last night I was playing GTA 5 and I joined up with a guy named [GT Removed] - Do not name and shame on the forums. and I was riding in his Adder. Long story short we split up after a while I went back to my apartment and his Adder was in my garage and my favorite car was gone because his Adder had replaced it. I was pretty upset because as you know hackers have made the game a lot less fun.
So I would like to know how to report this guy so 'hopefully' he will get banned. Thanks for your help!!
