Personal answer: No, copying TOS for your own website infringes their lawyer's copyright. "Documents written by a lawyer are protected by copyright as much as the work of any other writer"[1]
In the next season: Can we patent a particular way of protecting your website's legal rights ;) ? That would be great fun. We should patent the cease-and-desist letters, unfortunately there is far too much prior art on those...
