Oh yeah... I see that the speed run goals are gone now. Guess it is a glitch.
To answer your philosophical question: Without intent, there can be no cheating. If the goal could be completed over and over again and someone did it 500 times, I wouldn't buy the excuse of "Well GREE must have meant us to do it infinite times, right??" In that hypothetical case the right thing to do is stop and send a ticket.
