The See-Invisibility Exploit in Games: How it works 15 years ago
If you had that much power, you should have gotten your team to write something fun for the remaining 1% users of the hack you uncovered. Something like mark each player caught clicking on an invisible toon, wait until a certain time, and then WHABAM: Everyone caught gets a 5 day un-cleansable debuff that removes x% percent of their max health per second, but never making the killing blow. Put a cryptic tooltip for the debuff icon saying something like: Those who weild the eyes of the devil are now paying with their souls. Also, if their health drops below 10 percent, start automatically making them consume their potions at 10/sec!
