These are scam artists. Go look at their Terms and Conditions. They say they aren't responsible if they decide they don't feel like paying you or if your funds "go missing" or they just don't have the funds to pay you. Yet guarantee on the home page and on the app that you will be compensated for the work you put in. You essentially agree to free labor and the entire facade is just a farce. It's ridiculous. Customer services ignores emails. Report to BBB so others are aware of this scam.
