I think they would be happy to participate in some kind of audit. They surely want to organise their contributions in such a way as to produce the most benefit to the project. As for suggesting someone figure it out, I don't know why it happens and I would like to know. This is why I ask. I think knowing could benefit others and potentially also benefit me.
