ACORN question: Gatherers paid by hour or by registration?

[Gold Metal Flake]

Previously I had heard that ACORN employees who register people were paid by registration, which some took advantage of to defraud ACORN with phony registrations. Today, in this interview with Amy Goodman Bertha Lewis, Chief Organizer for ACORN, stated that the gatherers (my term) were paid hourly. Now, we know that some gatherers padded their records with bullshit registrations, and we know that ACORN had a system to weed out such foolishness and would even help to prosecute fraud, but what I want to know is how did this allegation that ACORN paid by the registration start? I've even heard in on Stephanie's show. So, mistake or disinformation floated out by whom?
