The fact that they have not been online means that they know they've been caught and are too embarrassed to admit what they have done. So do us a favor and take the stories down, Apologized to the authors of the stories you plagiarised, and if you want attention then please created something that has your own motives, and what you did is such childish behavior I'm pretty sure they teach you this in school. It's embarrassing that you were being reprimanded by someone who's probably the same age. You were trying to be bravado but failed when you finally got caught.
Good day to you Madam/Sir
