ToS can’t enforce completely arbitrary rules. They are still bound by the limitations of the law and the worst they can usually do is terminate your account.

And practically speaking they would be limited to telling you that you’re not welcome to come back and buy another one if you break those rules. They are not legally obligated to have you as a customer.

You can break the ToS all you want for how to use online services. The risk you take is that they decide they don’t want your money any more and turn off your account. In my opinion, that’s a fair trade.
