Bots are some DoorDash and Walmart Spark delivery gig workers' dirty secret

• "Bots," or apps that make it easier to claim orders, are proliferating on delivery gig apps.
• Some help workers pick up orders or shifts; others claim to provide hidden information about orders.
• Companies like Instacart and Walmart Spark say using bots violates their policies for contractors.

Last summer, a driver for DoorDash in Indiana heard from a fellow gig worker about an app that supposedly could show him a valuable detail about each order on the platform.
