It's to my understanding that TNT only records IPs at login and logout (read somewhere for trades/auctions is possible too, but that's irrelevant); meaning I could use whatever IPs one I'm logged in (and before logout), yes?
Yesterday, I had my VPN up and foolishly forgot about it, then accessed my main (which I normally only access by home IP) with the VPN's IP. I immediately left Neo without doing anything else.
Today I checked my main and I was logged out, had to re-login. If I didn't logout or do anything yesterday, shouldn't I still have been logged in, as if nothing happened?
I've done the same thing, had the same thing happen. IF it sets off any kind of flag, it hasn't ever fucked me over yet. They seem to be a little more lax when it comes to VPN's.
