captcha re-captcha'd

I'm getting slammed with stupid pharmacy comment spam (would anyone buying your possibly-contaminated drugs from scummy web pages stop please right now? You only encourage them!) so I've turned on the captcha for a day or so until they go pick on someone else.

I'm sorry to inconvenience you all, but it's hideously boring to go and delete all the spammy comments!

With any luck I can turn it off in a few days. Thanks for understanding.
