I agree that it's ultimately up to the GM, the idea of imposing a site wide system to do that judgement call for them is a bit silly.

If I GM an RP there are people I will not allow in it, and there are people I will accept without a sheet given my level of trust in them.  Every GM has to make that call based on their own experiences.
