Make #1 for a VERY VERY Competetive competitive keyword, using ONLY guest book links

I'm interested in the thoughts of others to this statement;

Climb to page one for a VERY VERY competitive keyword, using ONLY guest book links with keywords in the anchor text.

It is still happening with yahoo, I have seen sites ranking completely on blog comment spam and guestbookspam, But I doubt it works with google, I know one guy who is extensively doing this for couple of his sites and he reports those links are not working anymore for google,
