Good android apps that pays per sign up?

I've recently come across a money making android app that pays me $0.1 per referral sign up. I then used parallel space to sign up multiple times. Now my phone is running on a bot, and i have currently made $10. The problem is that i dont know if i can actually withdraw this money to my paypal account, since when i clicked on rewards and selected $5 paypal, it told me that it was delivered, and it could take 7 business days to send it to my paypal account. What im thinking is that they check my account and look at my history and then my referrals and they will definitely see something wrong. So just wondering if there are any other apps out there, that doesnt look for the same ip address, or see if its the same device.
