I reversed engineered the network protocol for a game.
I uploaded the source code to GitHub and made a post on UC Forums.

I kept getting bombarded with messages from the same person, it went something like this:

Him: "I can't get this hack to work, pls send finish hack, thanks"
Me: "First of all this is not a complete hack. You actually need to know how to code to use this library."
Guy: "Ok, can u help me make hack for game?"
To keep this short, I basically told him:
"No. Look through the code, learn it, use what you learned."

Couple of hours later he replied:
"Ok. I look through code but don't know how work. Send me code pls."
From the kindness of my heart I made a extremely simplified wrapper for the already simple code and sent him the project files.

He replies with: "Thank for hack, I not able make it work. I build I try inject game but no work. How to run dll file."

At that point I gave up...
