If you publish content on a website that willingly provides data to anonymous users of your site, even with a TOC on the site, the TOC is not enforceable if you cannot prove that the user explicitly agreed to the TOC. If you don’t know who the user is, you can’t prove that they agreed to your TOC.
Having a TOC is basically legal theater if you allow anonymous users. The implied threat is basically “IF we find out who you are” and you use the site in a way that is contrary to our published TOC, we will take action against you.
Your only recourse in that case is to pursue sites that are republishing your copyrighted content…because only at that point can you actually identify the party that may be misusing your site and it’s content.
