This spam attack shit was explained more than a month ago when my image hosting site was was attacked (since it housed the screen shots 'someone' did not want posted on GFY).
Since the recent banning. More attacks on other domains. My registrar. Among other threats.
Main splash page on ALL sites effected have explained the situation in detail and what you can do about it, other than crying on GFY that is. No offense to the O.P..
