I had my own stint doing this type of stuff on my different schools networks growing up and it too spawned an interest that’s led me to an entire career.
You shouldn’t feel bad - you learned, you got your kicks, and developed a conscious once you knew better. If dealing with some hacks in some of the games I played meant some curious kid got their start with programming it was well worth it.
What does piss me off are the people who turn it into a living to the extent where it becomes a plague - Warzone is a perfect example. Sure, the game still makes money, but the actual “scene” is fed up with it. I get that these same type of people/hacks are what you may have briefly been a part of, but it’s still not the same thing.
A kid contributing for fun is different than orchestrating the entire thing.
My take on it at least.
