I have a student who installed WP and has akismet properly configured. Despite that, she has gotten over 50,000 spam comments that were automatically approved. No idea how they got by Aksimet because they contain obvious spam words. Anyhow, I've helped her change the settings to change the automatic approvals, but we are looking for a plugin that will delete all approved comments. I've found a couple that will delete pending comments, but nothing so far that takes care of ones already posted. She'd rather not mess with phpMyAdmin (she's not that techy). Any suggestions aside from deleting them all by hand?
