I am always consistent with my survey info, but when I try to put info in for my husband or my daughter, I always use my email addy. My husband doesn't want any junk generated on his (I'm lucky if he'll do the survey for me!) and my daughters is very limited on what it will accept. It never occured to me that 3 different demograpics on the same addy could be considered fraudulent. They are consistently the same 3 sets of info.
