Well my main was frozen "for my own protection". I haven't logged on in a couple months though so it could have happened a while ago. Funny thing is last time I did anything nonlegit on it was 10 months ago. I used to RS 24/7 but my AB times were very safe. It's strange to go out like this but I figured this day would come sooner or later. I was ABing in stamps though...
Edit: thinking about it a little more I think I know why now. I've been moving around a lot this year (different countries, different homes, different IPs) so that may be the reason.
