I can't remember what the website is exactly and I am currently at work now so I won't be able to google it up but there was a person that use to do this except that he didn't use a bot but "bait" the scammers himself.

It is utterly hilarious. What he does is he replies to a "scam email" and most of the scammers will do anything once they see an actual human being replying to their spam email. He obviously leads them on and his signature move is to always try to get the scammer to post a picture of themselves with a card held up (for verification purposes of course) and the cards usually say stupid things like "ilikebukake". He collates all the emails, replies, pictures, etc and puts it up on the internet.

When I get home later, I will try and dig that site up.
