Thank you Victor for your kind, and professional response. Sorry, if I
offended anyone. I didn't want to necessarily incriminate anyone. I
just wanted to kind of find out if someone had any theories on doing
this test, or thoughts behind it. If they did it for research than I
am all for it.
I know that this wasn't secure, or protected from bots, or really
malicious persons. I thought about 1 vote per ip, or even a cookie, to
control the amount of votes. Maybe I'll do that for any future tests.
But what does the group think about the concept? Imagine a website
with artificial intelligence.

One fairly large problem comes up when limiting by IP. Many internal
networks NAT to one web IP. If several people in one business receive
an email about this site, and they go to vote, only one of them will be
able to do so. Even if there are header() functions that can pull the
original IP plus the web IP and limit off that, some businesses will not
support it and will not provide internal ips in the header packets. I
don't want to turn your thread into a NAT vs IP v6 war, so I'll stop
there. Just be aware that limiting by IP may not be the best way to
limit your visitors.
