Account sharing. It’s very widespread with these types of gig work apps.

Somebody who is able to get cleared sells or rents access to their account, presumably to people who wouldn’t be able to pass even the bare minimum vetting these companies perform on their contractors/employees. I.e. they’ll share their account with someone who doesn’t have a driver’s license or insurance, or is not able to work legally in the country for whatever reason. There may or may not be some exploitation factor involved as well. It’s the most dinkum, low-rent form of organize crime you can imagine. The account owner takes a cut of the proceeds and the net result is you wind up as some complete rando as your delivery driver.
