Scooper VS Craigslist Scammers

I have posted a few items on reno.craigslist.org (the best website ever!) and am so tired of all the lame scammers on there. I really need to find a way to fuck with them more than just leading them on for a while. Any ideas? The last guy (after I called him a Monkey Fucker) said that he was gunnin for me and would ruin me. I know that this is just a hallow threat but I would really like to be able to give him something back.... Hmmmm
