This is actually not a scammer. It's a market research group called NRG Research and their job is to recruit participants on behalf of other market researchers. They'll do a short survey to see if you meet eligibility criteria, then if you do you get invited to participate in a focus group for money. I've participated before and it's legit. I got like $100 just for talking about Netflix for an hour.
I have two questions. First, if you knew who this number belonged to, then why did you look it up? And two, how much did they pay you to post that lie here? It sure wasn't a $100.00.
