What is your policy on members of the same household joining?
Anyone can join as long as they fit the eligibility requirements set in our membership agreement. However, when people of the same household have their own accounts on Opt-in-Pays, it's sets off many red flags that can be seen as possible cheating. We have many checks in the system to not credit those that appear to be cheating and this may also affect those that are from the same household. Our recommendation is that if members of the same household use the same computer to access the internet, that they share an Opt-in-Pays account. Because of the checks in the system, you will not receive any more money by having more than one account within a household, you might actually receive less money from Opt-in-Pays.
Me and my mother also both have an account with LinkBurst, but we NEVER share a computer. When we happen to click a link at the same time, a message appears, telling me that someone in my household has already received credit in the past 30 seconds. So there definately ARE checks to see what computer is used.
We both have been a member for quite some time now, and neither of us is deleted for cheating. That proves that there must be other things wrong with your account than just thesame household...
