I have received Quite a few off those and at first I was really motivated to do my best to get in contact with them but nothing worked. The only benefit I can see is if you can possibly get them going in the business... If you cant get them to be active either, I don't see any benefit to you. But in defense of your up-line... They may not have known that the PSA was going to become inactive when they reassigned them to you.
