You can't force members to be active.
The best thing you can do is show people the money and then explain to them
what you do and how you do it, to make that money. Even then, there will be
referrals that won't always be active.
An idea would be to create a page something like this:
How would you like to earn an extra $100.00 and more a month?
-No selling
-No begging family and friends
-No sponsoring
Simple fun system that allows you to earn extra money every day
for doing simple things in your spare time such as completing brief
surveys, watching videos, completing simple tasks, viewing brief
ads. In addition, you can get paid twice every week to your paypal
account OR by check OR even (gift card/debit card arriving).
