Lisa found a useful little tool.
A link to the spambot stopper on your blog should be picked up by those horrible little email leech programs, you know the ones that find your address on the web and then send you loads of rubbish. Any leech that follows this link gets trapped in an infinite loop of randomly generated false email addresses. Whilst its stuck there it can't harvest any other addresses and whilst it sending to those false addresses it can't be bothering us know can it?
Go on, you know it makes sense.... add the link to your blog as well.
My only concern is; what does this do to Google search bots?
