Caller said that he was conducting a political survey on public opinion on tax policies. However, he said that before he could start the survey, that I had to first answer a bunch of personal questions about myself, to determine if I was a member of the target audience the survey was meant to poll.
That really sounded rather fishy and improper to me, so I hung up. I would not trust these people, if I were you. What they said to me was very suspicious, in my opinion.
