Firstly with 8 million accounts I doubt they'd notice.

Second, you're not doing anything wrong, so even if the worst case scenario happens (you get suspended) call them up and explain, they're not evil bastards lah. And they want your money.

On the other hand, if your IP when logging on constantly changes (i.e. Australia - Malaysia - Australia - Malaysia) then it'll become quite obvious that you're sharing your account, which is unfortunately against the TOS.

I do know of people on my server who were suspended/banned because of account sharing, but even then only because someone reported them.

Bottom line, berani kerana benar lah.
