Recently I joined bing rewards and made like 5 accounts. I used the refer a friend to refer each new account to the next. Once each reached 200 points, the account above it would get 500, giving them near gold status and making them like $10 dollars each if you went a little farther. I suggest using the Bing Bot if you want to make a little extra dough with free time! It is all in gift cards mind you, but Amazon or Microsoft or Starbucks isn't too bad.
