Perk is largely a 'run videos on your mobile device' program.

You can run 3-4 devices per account at one time, so if you can find some $10 smartphones, you can connect them to your (unlimited data) home wifi network and just let them roll until they crash, which is unfortunately often these days. Reddit probably has some good tutorials in how to maximize earning from them.
