help this guy has put my profile pictures on porn websites and is black mailing me?

My friend went through an extremely similar situation, funny really. What you have to is go on some video chat website (omegle is pretty good) find someone with an embarrassingly small dick, take a picture of it, and make a profile of that guy who's harassing you, passing of those pictures as pictures of him. Do exactly what he does to you, and watch as he frantically denies the pictures. Of course, this is an extremely weird thing to do and I'd probably be too grossed out to do it myself, but my friend went through with it and oh my god it was hilarious. The guy shut right up. Gain some power over the situation and say you'll keep doing it if he does.

As for the threats, my friend had the same problem. Honestly, he's most likely not going to go through with it. You can call the police if you truly feel threatened. Just keep the evidence of his threats, the best way to stop blackmail is blackmail.
