This guy I met a few years ago online started chatting me up. We became friends since we shared some interests, but I later found out he's really messed up in the head. He had a streak of causing people serious problems, namely he boasted about swatting people's houses in the US because he lives in Germany - outside of US jurisdiction. I realized he was trying to get my information to do the same with me so I cut off contact with him.
Later I come to find he had made multiple alt accounts to get at me. He made all kinds of malicious threats. An example being, he once said he was going to steal my identity, pretend to be me and post incriminating lies to get me swatted, stuff like, "Hey, I'm trying to get materials for making a bomb, can anyone point me in the right direction?"
But I'm not a violent person and I'd never do anything stupid like that.
Anyway, recently he found out about my work on tapas and is now saying stuff to one of my other friends, stuff like, "Tell him to finish his book already so I can take it and publish it."
I figure it's just empty words and more harassment, but he's pretty dedicated to messing with me so I'm wondering if he'd actually type it out word for word, or if he's found some way to copy and paste, or if he can legally get away with something like that especially since he lives in another country. The strange thing is, I don't respond to him anymore and yet he still tries to harass me (he's been doing this for a couple years). It makes me think he's actually serious, since what kind of troll continues to harass without stimulation from his victim?
