Of course I've been curios, especially on those linux. But I did it on loopback , with unplugged ethernet and after that I deleted all created/modified files and NEVER in multiplayer enviroment . As soon as you cross your "router" with enabled cheat/hack or any other shit , you are a cheater . Thats my internal policy :D.
BTW: I know one guy that was "testing" hack on his private server .To these days, he is still hw banned. :D
Do you think that its cruel? I don't . If you don't know how to test them , don't test them.
