Basically, the simplest and most pure definition is that gang stalking is multiple bullies attacking one person.
There doesn't need to be government involvement. No electronic weapons. No huge amounts of money involved. No Satan, or Jesus, or UFO conspiracies.
Just multiple bullies attacking an individual.
