Both are games. A "Googlewhack", for the uninitiated, is a search result of just one item using the Google search engine. I've never been able to come up with one myself but I'm also really, really busy. An example of a googlewhack is "spoonable snowdrops". At least for now, if you enter that in your search field, you'll just get the one result. I found it listed at the http://www.googlewhack.com/ website. And Dave Gorman, a brilliant British comedian and stage-performer, actually turned the silly pursuit of the Googlewhack into an amazing, round the world chase and stage show about his own role in googlewhacking. My husband and I saw him when he came to UCLA and it was a very fun evening!
The Googlewhack makes an odd sort of appearance in the November State of Spam Report from Symantec's Security Response team. Apparently, our fiendish foe, the spammer, is trying to defeat spam filters by using Google search result fields to direct the victim to their site, without actually revealing the site in their spam email. And that mechanism can only work when employing a googlewhack or google's "I feel lucky" feature to limit the result to their site. Now that spam makes up 70.5% of all email in the world, it makes fighting these new methods sometimes feel a bit like "whack-a-mole," where as soon as you pound one method down into its hole, another one pops up in its place.
Get to know the delete key really well because it's your true best friend in dealing with this spam scourge. Don't open them, don't click any links and don't fall for the various methods the spammers are employing to trick you. You can read more about this in the Spam report which is really easy to understand and I highly recommend it to all.
