Hi, A pretty easy solution exists and is to use "http://www.captcha.net/" images before locking the account.
The obvious problem is that a visually-challenged user is screwed. The not-so-obvious problem is that although it "proves" the person is a person, it doesn't prove that the person who entered the response is the "alledged person or script" you sent the image to. Some spammers have found a way to deal with these - they grab the image, and pass it through to some *other* user as a captcha to get into a "free porn" site or similar. So the user sees it, types it in for the spammer, and then the spammer redirects the response to whoever originally sent it.
