It's not about being serious. If you use hacks against other people, there's a lot of chance you'll take away their fun. Why would you have more reason to have fun then everyone else ....
On the other side I can a little bit understand you, but it still remains a bad move.
You know if I run a server that allows hacks and cheats, make this public with access to info on the hacks and how to implement them it will influence development, a spark to new ideas some not so great but it still allows anyone to be creative with the game in hand. I'm not here to play this game as serious play only, I'd like to be able to have fun with the development of new mods and or so called hacks for fun game play instead of just being handed the same old gun or map.
