It’s when there is a deliberate attempt to get under the skin of the target, who is a stranger (when it’s someone the perpetrator knows, it could be better described as cyber-bullying). It’s usually directed at celebrities, journalists, politicians and sometimes people who find themselves in the public spotlight without ever having sought it.
