I was already in my 20s, so arguably too old for neopets when I discovered it and was subsequently banned.
I found a flaw in an archery game that would allow me to always bullseye. It would only work in Firefox. I didn't have to do anything outside the normal interface.
I guess they decided to ban every archer that did too well. It was fine. I didn't feel compelled to try and return.
I remember that same bug! It was something about timing and angle that always resulted in a bullseye. Must have been pretty simple for me, a 10 year old, to figure out.
I never got banned from it though. But I later forgot my password and moved on from my comcast.net email address (there were no password managers back then), and grew up, so effectively the same thing.
