Terms of service were meant to be broken, they are a once-sided agreement that the other party never needs to uphold, there are no consequences for them if they don't. So I say the moment they try to screw you over give them a good punch in the face, there are some nasty ways to do that to online entities, some illegal, others just petty, some in grey areas (in real free countries none of them are illegal, because corporations aren't protected in places like that).
