Well so how does it affect other people?
It makes them rage and makes them angry and makes them swear
But there is one thing on there mind REVENGE so what do they do?
They turn into griefers to make other people experince the pain that they have experinced!
But where does griefing originate form? Griefing originates from people who have really sucky lives or who hate them selfs so much so they start griefing to make them selfs pleased!
So in short griefing is like a virus it orignates from people with sucky lives then gets carried to people wanting revenge!
So griefing creates more greifers!
