Sure you can. TOS docs are full of non legally enforceable wishful thinking bullshit, especially when they're written by an American company providing services to me in Europe. Most of the time they just expect (correctly) that they'll never get challenged in court over it.
Even if it isn't enforceable from a usage perspective, it is from a provider perspective, meaning they can also simply deny their service to anyone they discover breaking said terms. And there's nothing anyone can do about it.
