Not really online but I got kicked out of my Year-8 (2nd Year of Senior School) IT Class for sending IR signals with my phone to flip the Projectors output, they didn’t know what was wrong until someone told
yesterday i put some simple script in notepad in my shool and my computer's dvd drive was opening and closing itself and the teacher did not know how to stop it and the other thought there was a ghost or smthng.
We used chrome books in grade 9. My friend had the class list (Has student ID on the list which we use for passwords, dumb i know right) and we logged into this one guys account and changed his background to a nude man. We saw it change on his screen as soon as we changed it. He had google open so he didnt realize but the side bar which is kinda clear showed it. We started laughing and he turned around and said "What" but we said nothing. He realized after closing google chrome and he want ballistic xd. He stormed off into the hall yelling lmfao
outcome: Principle kinda knew it was us because my friend and I did that kind of stuff to computers in grade 9. We had a serious talk. lol
