GANG STALKING

Gangstalking: ... a form of community mobbing and organised stalking combined. Just like you have workplace mobbing, and online mobbing, which are both fully recognised (as legitimate), this is the community form.
Gang stalking is organised harassment at it's best. It is the targeting of an individual for revenge, jealousy, sport, or to keep them quite, etc.
It's a psychological attack that can completely destroy a persons life, while leaving little or no evidence to incriminate the perpetrators.
