Does anyone know which social networking sites do NOT add no-follow tags? Myspace definitely provides zero help in they now re-direct all links through themselves.
I don't think bebo does, Although not 100% sure. You can thank phishing and overtly persistant spammers (like macy gift card spam) for the myspace redirect links. Myspace has turned into sewer imo.. Facebook doesn't really matter as much. The site can't really be crawled by any search engines. Facebook is clean.
