A stalker found me thru eBay. Please help!?

Ok, so I have been buying a bunch of disney pins off of eBay so my kids have pins to trade during our trip to WDW in May. So anyways, I bought a mystery lot of pins from this guy and paid thru PayPal, and was simply expecting my purchase thu the mail, like all my others. This creep gets a hold of my email account and has been sending me perverted messages because of the account name. (nurse....) So, now this creep has my email address, home address, and possibly my phone number as well. I'm kicking my for not getting a p.o. box for eBay now. How can I report this crap to eBay? I have the emails and am reluctant to get the cops involved but I have smaller kids, and am a bit nervous. I'm very serious about this!!!
