Well i don´t worry too much about controlling the house rule.
I guess we all play to have fun and clamhoarding or mass devils aren´t fun to most players, because they make the endgame quite tedious, yet you have to do it to stay competitive.

I would just trust that everyone sticks to the house rules, to allow for a more interesting game.
If someone would break them, you could always use the master password to have a look if something looks very suspicious.

If there are any people here who would not want to play with a restriction rule, they can say it right here. And if it´s a significant amount of the players(3-4 at least) we just play without restrictions.
