I believe that the AMA statement of Ethics does address this issue.It states that one should always do no harm, honesty, fairness, show responsibility and have transparency.
The poll was to gather specific information about whether or not someone would buy a particular car. I doubt if when taking the poll the poller indicted that they would be disclosing the participants personal information.
The AMA Statement of Ethics deals specifically with: do no harm, honesty, responsibility and fairness. Disclosure of a participants personal information could do harm, would not be honest and there would be a definite lack of transparency.
