In my opinion it's good that Facebook deletes fast fake accounts- I'd totally hate if somebody has same name as I do (1 in Finland does, but doesn't live at the same place though.) and would live at the same place.. so confusing. =I
I guess Yoshiki didn't get pissed off or anything,, though I assume that he didn't like it in anyway. Let's hope there won't be any fake Facebook accounts of X japan's member nor any band/person.
