Click fraud prevention?

[A. Smith]

I encountered something that, after all the discussions about click fraud, I thought I'd post this.

I was doing a search and this page came up. I clicked on "Nautical bathroom", the link from Shopzilla ang got: 65.39.170.123/search.php?43140;1926686496
Well, I can't seem to get that Anti-fraud page to come up again. Here's what it said:
"AntiCheat Sheet
Please take a moment and help us uncover click cheaters. Click on the phrase you've search below and get redirected immediately to the search result url."
Then it had the phrase I was searching and a few others. Also had a box where I could choose that I didn't search or clicked on anything, and was redirected without my agreement. Finally a last box where I could choose that I've searched for a different phrase.

Looks like some people are taking action against click fraud. Comments?
