Just in the past few months there's been 1ronyman, analfarmer and my favorite - well I guess I shouldn't name him in case it violates rules - but some guy that yolo'd his student loans by accidentally buying puts and then tried to convince people he was a good trader.
I also just remembered that time someone tried to share his success with SquareSpace and it turned out he'd bought Square stocks instead by accident and didn't even realize it.
