Black hat on your White hat site

What are the risks if you take some of your backlinks from possibly articles, squido, propeller, or whatever. and link spam the shit out of them.

If the backlink gets dropped from the search engines, who cares.

Would this be a safe and or effective way to boost your search engine ranks on a white hat site, by building strength to your backlinks.

do it, but mix it with whitehat links. Make sure that there are more white hat links than blackhat links.

search engines will consider only quality links. the others won't help.

Thanks for the input, My thought was to take my backlinks and submit them to dirrectories, bookmarking and such. Nothing like ffa, of guestbook spaming.

I guess more quality links to my backlinks, but ones that can be automated.
