I've had a mix game to game. One game I had like 5 running into the kicker/punter penalties (from non-usered player).
Other games I don't have any defenders come close to doing it. It's def frustrating when it happens a few times in a close game but I just chalk it up to young dumb players being young and dumb.
Since our only options are to turn the penalty off or on, if you really wanted to try and get any change done it would be through like pass blocking which would more negatively affect the overall game just to stop a few penalties.
If it bugs you I'd just disable it tbh.
