It's really not hard to tell people using cheats and scripts, plus they are the ones who cry the most when you call them out for it.

I totally agree with Anubis. If it can't be used online, why is it so private? What's the point? Why can't everyone use it and have fun offline? Makes me think that it actually does work online, which is shady and pretty lame.

I can confirm such a way to do it online exists.  However it greatly lags the game during your turn so there is no way you wouldn't notice somebody using it.
