I have seen this numerous times. The latest was in the kids division my cousin shoots a deep double leg, the kid bails out and goes to the mat hard. The official rules it a slam. The other coaches go out to the kid and ask him "are you ok" the kid responds "yes" and starts to get up. One of the coaches asked the official "was that legal" the official told him it was a slam. Then all of a sudden the kid is back on the mat injured and can't continue. This is happening at every level unfortunately.

If it is flagrant and with the intent to hurt the other wrestler it is a great rule, but it is way to easy to win a match on a judgment call by an official who has make the call in the heat of the moment.
