I know of some people who got bullied in social situations and they didn't have the balls to react, so they started cheating. ( not gonna name the person tho
)
I'm quite sure there's a few people out there who suffer from some sort of social depression and have to make them payback in whatever way they can, keeping in mind that cheating online is an anonymous way of fighting rules...the same rules that many people don't follow in real life and cause problems to most of these bully-victims
