Those of you with deactivated accounts... Are you using multiple emails and have 2 or more accounts?
Years ago, I was doing surveys for both my husband and my own account from the same computer and they inactivated the accounts. I wrote and asked why and they said it was because 1 computer was being used for 2 accounts and that we had the same address. We always redeemed to our own hotel or airline accounts.
I responded that we are married, live in the same house, and use the same computer. They reactivated the accounts.
Another time they wanted to verify where we lived and had to send a copy of our driver's licenses.
Since the deactivation, I never use the same computer to respond to surveys from both of our accounts. I generally use my work computer for my husband's account (or my ipad) and my own desktop for my account (sometimes my phone).
Haven't had a problem since.
