I Hate Being Used

All I ask is for the people to do something about a stalkerish troll and what happens? They pretty much treat me like dirt, use me as their personal laughing stock and make my Ol life miserable. Then they extort me and trick me into almost deleting my system32 drive and then they post my embarrassing videos and the like all over the internet for all to see and hack my accounts. One of them pretty much promised to get this to stop but only if I got them robot related pornography.
