Those comments should have been removed within 10 minutes of entry, but I have revised the process to remove them at the point of entry with the remaining post-clean process in place. I can't stop someone from placing a comment on your blog and with the coComment feature turn on and no Captcha, it is an open door for automation. I suggest you flip the captcha flag back on via admin to help protect you blog more. Spamming right now is our #1 issue we are working out solutions for.
