Well, several hacking attempts on seocontest2008-sphere.com (including brute forcing attempts on our WP console and injections), SQL injection attempts on both seocontest2008-sphere.com and seocontest2008.com, duplicate content attack now on seocontest2008.com, ... (what next??)
It seems that there are bad-asses on this contest, who are trying to down the leaders... It's the first time I see such things on a SEO contest, I don't know what is different with this one, and I just hope this will not be a tendency on future contests.
Benj, your site is strong, and it always was during the whole contest, I think that this attack will not affect your site. I hope that your site won't drop, and that you'll remain on... 2nd place (just kidding
Good luck) !
