So I've read a lot on this forum regarding backlinking, and one thing always sticks out, "Don't spam or the Googs will penalize you". That got me thinking. What's to stop you from absolutely SPAMMING links? I mean really spamming them as hard as possible. But not to any of your sites, to your competition. The Google machine catches them, which is really you acting as them, and penalizes them down in the ranks, bringing you up comparatively. Other than the obvious moral issues, I said this requires the blackest of hats, what's to stop somebody(don't look at me) from doing this?
