So yeah, read the wiki's policy. I think you misunderstood the question. The TOU allows users  to remove anything they want from their talk pages. Wiki admins (or anyone really) are also allowed to restore it, if it doesn't violate the TOU or even block the user from editing the page if they keep removing it, and the admins want it kept for any ludicrous reason.
