I see you didn't add the black list. Well, the guy (Evilsnoopy) apparently deleted his char. I'm still guessing he might have some alts to wreak havoc with. Although I can't be sure.
I think it was three days ago when I reported him.
I haven't still gotten any response from CS, but I'll update the info here as soon as I get it.
Atleast I learned a valuable lesson from this case, as SWTOR is my first MMO. Guess all I can do now is blame it on the boogie.
