I agree. But the internet age feels like it unfortunately has made this much more difficult than it should be. People over share on social media and make themselves too visible because they aren't aware of the consequences- or don't assume there are people out there sociopathic enough to harass someone to that extent. The pool of potential suspects when they're acting anonymously has grown from whoever is in your local community to whoever has an internet connection in the world. Not uncommon to hear of such harassment, blackmailing cases and such where the perpetrator doesn't even live in your own country where police could do anything about it even if they had their name and real evidence.
