There is a few options:
#1 - download the block # app on your phone.
#2 - send communications to paypal
#3 - un-fog his phone # so some of us can have fun with him too
#4 - wait for himto show up at your house and give him 2 seconds to get the F*&k off your property, or you are going to go all 2nd amendment on him.
I like 3 and 4
