Somehow my superadmin got locked out as a spammer

I get the message “Error: your account has been identified as a spammer”. I know how to move around in phpmyadmin, but don’t know where to go exactly to fix this. I’ve tried renaming the plugins folder to deactivate all plugins, but am still unable to login. Meanwhile I’ve got multisite splogs multiplying. My best guess as to what happened was that my new blog template was adding admin as a user to some of the splogs being created, and so when I identified them as splog, I identified myself as a spammer? I don’t know. I’ve tried changing my password and everything else I can think of, I’m ready for help. I’m running multisite, buddypress, and a whole host of premium plugins, everythings up-to-date.
