The purpose of user talk pages have nothing to do with the TOU, other than the obvious "don't harass users/upload porn/use it for illegal purposes". Each wiki has their own policies regarding the use of a user talkpage, so you need to check the wiki's policies regarding user talkpage use (if no policy exists on the wiki, ask a local sysop, as they will possibly have an unwritten rule on talkpage use).

However, despite wiki's having their own policy on their use, a large number of wiki's that use talkpages over walls don't allow users to remove messages from there, unless it's a message just being used for unreasonable harassment of the user, as talkpages are public communications areas for users of the wiki to leave messages about editing practices or solving disputes. Unlike message walls, user talkpages generally do not belong to the user but are community property. Therefore, most wiki's will revert any edits whereby you remove talkpage posts (other than the generally accepted practice of archiving its contents to a subpage, but making sure a link to the archives exists).

I have no idea why Dessamator is directing people to Wikia Staff and the contact form for this. They would simply say that it's up to local wiki's to determine what you can use the talkpage for.
