All of my referrals have 0 Swagbucks earned and they all signed up 6-5 days ago

I have had 10 referrals in a day that all signed up 6-5 days ago and it is showing that they have 0 Swagbucks. shouldn't at least some of them have earned some Swagbucks by now? Oh and one more question if they refer people and earn Swagbucks from then would I still be getting a portion of the person they referred Swagbucks? like 1% if my calculations are correct.
