Can visitors vote more than once?
Some of my visitors complain that they’ve never voted before, but still get a message that they’ve already voted! If you enable IP blocking, the IP address of the voter is recorded. If someone with the same IP tries to vote again, their vote will not count. If you are using your poll on a site where people access it from behind a firewall, many of your visitors may have the same IP address. For this reason, you should disable IP blocking and only enable cookie blocking.
