This wouldn't supersede any violations of the ToS, though. I guess it would mean they can't sue you (maybe?) but they could still kick you off their service. Could they still go after you for breach of contract?
ToS aren't signed. They are terms of service, not license agreements.
ToS merely need to be disclosed, and the site cna decline service if you violate the terms. A license agreement may subject you to penalties for violating the agreement.
