Who is The Mall Squad? (Ref. sheets)

How do 5 strange drones become the cornerstone of Copper-9's economy? You know, I'm not all too sure myself. The Mall Squad has many services for other drones to trade for, buy, or lend some oil for. With 3 members needing to drink oil, it was preferred in their early days, until they scavenged a huge supply that they later share with other passive DD's & solver users alike.
