Do you think it's OK to have a family member who likes to answer surveys do some of these surveys for me? After trying a few we've noticed a lot more surveys are offered, possibly due to his younger age.

Strangely the age on the profile also changed to his age even though no one changed it. Is the supposedly confidential survey data applied to the Opinion Miles profile? If so do you think it could also be compared to United TSA data to compare birth dates, somehow jeopardizing miles which have been earned?
