Guy messaging me telling me he saw me in porn

So this random guy that I'm not even friends with messaged me and told me he bought a phone that had porn with me in it. He told me to send him nudes or else he was going to post my nudes on Facebook. 
Lmao. Okay, so I ask him to show me the pictures he had of me and he just kept saying he couldn't. Then all the sudden he starts sending me pictures of a dick. 
Um, I'm pretty postive I don't have a dick so I ask him wtf he's doing and he then tells me that I should send him my nudes because he sent his. I'm about to hunt his ass down and leave a bag of burning shit on his front porch. He sounds like a nasty pedophile. 
As far as posting my nudes, that's okay. I'll just call the cops and charge him with blackmailing me lol 
And nah, I was not in the porno lmao
