Really a good question! I haven't used any cheating categories for a few years now. It did me really good. I advise the same to the other members of the forum. However, I love to share experiences here.
it just feels great to have advantage over someone else , feeling of godlike , also i like to get things done quickly , for example in mmorpgs , farm bots and damage hack really helps to climb in the game quickly as for someone who plays legit
