Given how "easy" these "agreements" are for most people to discover, I've always liked the idea of a client-side HTTP header: X-Client-ToS-Policy: TOS_ACCEPT=NONE,"By providing me a web page, you agree that our relationship has no additional terms or agreements beyond those already established in law." It's machine readable and provided before the page is delivered, so it should be at least as enforcible as the nonsense "terms" businesses seem to like these days.
