This is something your league must deal with. As far as I have been able to search, there isn't any rule against this, NOT that it is right, I don't think it was ever really looked at for a rule.
Your league can, but be careful, set a rule against this. Keeping in mind, everyone has a "bad night" so I'd be careful when you design a rule about pin count vs. scores thrown, but your league has the 'power' to set rules against this. I know (my wife is president of our league) we are looking at a rule about this. Not sure the exact pin count before it is determined to be sandbag, but we're working on it.
As I said, everyone can have a bad night, but I think , to 'throw' a game, is just plain stupid. I am against the lane..pins..that's how I approach the game, me against the equipment. I can not change or effect what another player shoots, like in golf, but I can control, to a point, what I shoot and that's the point of the game, for me.
I'm done
