It doesn't take a genius to realize that Engadget is in on the vote fixing.
Any competent site would have locked it down to a single vote per IP address. Sure, it's still possible to get around that with proxies or by changing your MAC address, but it's not going to be as efficient or quick as clearing your cookies, or just disabling cookies altogether.
What's going to happen:
Contest ends. Engadget claims that Motorola Droid cheated and Zune HD cheated, and that all iPhone/Apple votes were legitimate. I don't doubt that people have cheated while voting for the Droid. I'm sure some did. And even as a Zune HD fan myself, I don't think the Zune had 9211 fans worldwide, which is what it's vote count is currently at. It's keeping up better with the iPod Touch 3G than the Droid is with the iPhone. That is clearly some vote fraud. And then, of course, it's pretty obvious that the iPhone votes are illegitimate.
How to ensure your beloved iPhone still wins, Engadget style:
1. Make it easy to cheat, but say you'll examine the results for signs of cheating.
2. Cheat and vote for iPhone/let people cheat for iPhone.
3. Come out and say that anything but the iPhone cheated. Offer no proof. But who cares? Your beloved iPhone won.
4. ?????
5. Profit.
Engadget just needs to be internet nuked. This bull**** is getting a little old.
