Forum posts are not of any use at all if the forum does not relate in some way to the link posted.
A good example of this is the Lunarforum

Admin's and moderators check each and every post, and links in threads and signatures used to non-Lunarpages hosted websites are edited.
Lunarpages forum is for the benefit of Lunarpages hosted websites
and not spam posts from every Tom
