FrontPage Guestbook, Board, Forms spam

The main raison for people spamming your FrontPage Guestbook, Forum/Board or forms is that the search engine Google, counts every "back link" (i.e. link pointing to these SPAM sites) as a positive vote. So if they can get a link to their site on your Guestbook, Google will interpret this as an "endorsement" of their site and give then additional "importance".

This spamming activity is especially common nowadays since they are thousands of automated scripts looking for FrontPage (or not, they will try to spam anything really...) guestbooks, boards, or forms to post SPAM links.
