will submitting for FFA's will increase my serps for a while? until google finds out and bans my site? how long will it take for google to find out?
not likely your site will be banned for this. FFA links are less merit, and have very very low PR juice. signup FFA through new/unuse email only, expect lots of spam frm it.
All false, if that was the case then it would be so easy to destroy the rankings of your competitors by submitting them to FFAs.
