PayPal payment scam

I put an ad on Craigslist and have received so many scam responses! Omg. I said no cashiers checks and one guy said he could do PayPal so I gave him my PayPal address. Imagine my surprise when his supposed payment via PayPal was actually two emails (that appeared in my junk folder no less) with instructions on how to get ny money via PayPal. Seriously?! How exactly do I report this scumbag and to whom?! I use PayPal pretty much exclusively so I am well-aware of how it works…
