Zelly... I guess FB scores are a possibility. But they are both pretty low as follows.

The account that is still selling reasonably OK was started in July 2014 and has a FB score of 89 (100%).

The other one that has dried up was started in Sept 2014 and has a score of 28 (100%)

This is the one PayPal put the funds hold on. The other one has never had anything put on hold.

It was doing OK up until I put in the FOS claim.
