They do monitor, However there is limits, I have successfully shared with about 5+ People, with no consequence so far. It's almost been half a year.

Usually when IP's get a lot, they will be suspicious, and even THEN, its REALLY easy to get it back.

Just write an angry email explaining that you use it at work, home, etc.. have dynamic ip, or use proxies.

They can't say shit, cause you paid for it. The email does work, they will return your account back. But don't push it..!
