It is safe to AoB as long as you don't send an absurd score. I AoB all the time. I've gotten reviewed multiple times. You have to play it smart. If the game would normally take awhile to play then you wait the normal amount of time and then send. As long as the AoB does not alter the point value too high so the game looks unrealistic as in terms to scoring faster than normal then you should be fine. Don't be afraid if they review you. Nothing will happen if you play it safe.
