Crazy part is the shut down all accounts of anyone who was an AU on my card including spouse and my parents.

$1600+ in points are gone, but I've got their Executive Office working to get them back after an FTC complaint.

Miles per Day has a post on his similar Barclay shutdown as well. My theory is the Buxx and Serve house cleanings happening at the same time are not a coincidence and that there may be collusion between banks leading to shutdowns of accounts that have touched these products.
