LeaverBuster Warning asks for the impossible.

The problem here is really the last line of the warning:

"Do you agree not to leave any further games?"

You know it's not possible for people to commit to that. Even if they ignore family obligations (in my friends case, his wife's water broke), there's still the chance that their internet will fail them (as was the case for me and my wife in the screenshot attached).

The phrase should be re-worked. Perhaps "Do you understand that leaving games in the future may incur penalties?", or something along those lines.
