Hmm...ya. Has anybody multi-accounted the advent calendar?? If so, have you gotten frozen if you didn't use proxies? I'm thinking about using it on a few accounts in an effort to get the winter site theme...but i dont have any proxies....wondering if TNT cracks down hard on this or what?
I used it on three accounts including main, and so far i'm fine. I am like you though, only doing it for the avatar & theme. I can honestly care less about the 300NP or the junk they give o_o I would say if you don't use like 50 accounts, chances of being iced isn't likely. It can also be assumed that maybe you have more than one person playing at your home right? I'd say as long as you keep it maybe under 4-5 accounts, it'd be good. I collect with multiple accounts every year.
Back in the my old days, I had about 4 accounts which I clicked Advent Calendar site everyday. I think the freeze rate is 20% at most
