How could an adult use cheats, hoping they wouldn't be caught? It's just stupid, in my opinion.
P.S. By the way, for those who talk about a mistake...
What is a mistake? Mistakes are usually made due to ignorance. This person, however, perfectly knew what he was doing, he perfectly knew what a cheat code was and what a serious violation it is.
I repeat, all of this was done by him consciously.
In a sober mind and with a clear memory. :)
So, what excuses can there be???
