I read a couple of the voting rules...here is what it says :
1.) Each contestant and visitor to the site may only vote once per photo. Usually your computer will have "cookies" enabled which allows us to track the amount of times you vote. If cookies have been disabled on your computer, your vote will not count. Big Picture d/b/a photowow.com reserves the right to remove any votes it believes were submitted illegitimately.
4.) In order to keep the voting process as fair as possible, a formula has been derived which does not count a random number of low votes. This is to avoid contestants and their friends from voting low on other contestants in order to increase their entrant's odds of winning.
I just copy and pasted the 2 that seemed like a concern for people. Hope this helps.
And I hope .Finn stays number #1, I was able to vote from work and from home.
