Farming?

[FudgyDRS]

1. Do NOT abuse extra lives or extra continues. Anything that allows you to start an infinite or near infinite point loop or rewards you for playing badly is not accepted. If a game gives you an extra life every time you play a level, you may collect that extra life but you should only use it once. If you collect the same extra life multiple times then you would have lives remaining when you submit your score.
2. Do NOT Farm, Grind or Leech. Do NOT repeatedly kill the same respawning enemies or repeatedly collect the same respawning treasure without naturally progressing through the game. If the game has a limit such as a timer that would prevent you from doing this for very long then you may break this rule.

Would these be exceptions to these rules:
-Infinite lives exploit with a shell on Super Mario; takes no time at all to get max lives.
-You about to beat the game, but your score isn't quite high enough to beat the High score and but farming at the end gives you that little extra boost, like on Mega Man or similar platformers?

If these arn't exception, what are if any (excluding the one mentioned in 2)?
