I'm more interested in how everyone seems to be pm'd so often by random people. Personally, I've always kept my private chat set to 'on', yet the messages I receive from people I don't know never really surpasses more than once or twice a month, if that. I would say that I'm decently high leveled as well, and I use highly populated areas quite often. For me, it wouldn't matter if my private chat was on friends only or not, the amount of pm's from people outside of my friends list is negligible at best.
