You really should read your TOS, if not at least skim it. Most have language like this in it:
THIS IS A CONTRACT. PLEASE READ THESE TERMS CAREFULLY. IF YOU DO NOT AGREE TO THESE TERMS DO NOT USE THE SERVICE AND CONTACT US IMMEDIATELY TO TERMINATE IT.
By specifically stating what you are agreeing to is a contract, you're legally bound by the terms set forth therein. Whether a court of law and judge agrees with that is a separate matter. However, for simplicity, it is a binding, legal contract.
