You are harassing him and every person you contacted thinking you are helping them. Seriously, move on. If you guys were from the same country, I'd recommend him going to the police. People like you are dangerous.
Nobody is harassing him, people are talking, and people are free to talk about a person who was abusive, it's something called communication. Something you're not used to in that Telegram group.
At this point it's the opposite of harassment, people are actually saying how he should be avoided at all costs and how it's painful to deal with him.
