Source?

Pure anecdata. However, the change from the first two days I multi-apped and made almost 3 times my usual hourly rate, to the following weekend, when

>neither app would send me orders for up to half an hour

>as soon as one had assigned me and order, the other would start sending my multiple per minute

>all of these orders were either comically low-compensation (no tip), a 15-minute-plus drive away from the order I'd just accepted (to areas it had never sent me before), or both

was marked.
