True.

A friend of mine broke up with someone with a bad drug habit and he paid some scary friends of his to stalk, scare, and cause property damage, and follow her around for months. Scary AF.

Though I once had a stalker that was not very covert at one point. He once proudly talked about something he did while stalking me. That backfired on him when he realized everyone thought he was a creep instead of trying to make me look bad.
