What is a phone farm?

A phone farm is a rack of physical smartphones driven by software rather than by hand, used to run many social media accounts at once. Each phone has its own hardware identity, so platforms see real devices.

A phone farm, or device farm, is a set of physical phones connected to a controlling computer. Software drives them: tapping, swiping, typing and reading the screen, the same actions a person would perform, executed on a schedule.

The point is the hardware. Platforms fingerprint the device: model, identifiers, sensors, behaviour. A real phone passes because it is a real phone. An emulator has to lie about all of it, and the lie is detectable.

In OFM the usual build is iPhones, three Instagram accounts per phone, each account posting reels and stories on its own rhythm. Fifty phones is a hundred and fifty accounts running without anyone sitting in front of them.
