New version of google-bombing

I have been google-bombed by auto-commenting scripts. Here's another technique reported by kasia in a nutshell:

Remember the good old days when you could make a search phrase on google point to a certain page? Who can forget when the phrase 'go to hell' brought you the Microsoft site as the first hit. That was referred to as 'google bombing'.. simply linking to a specific site with a specific phrase making google ranking for that phrase increase for that site (but you all knew that).

Now there's a new version! Everyone loves their statistics.. of course.. me included.. but many forget, that allowing Google to index your statistics is totally useless for you and the person searching.. and guess what.

Now not only are the bad guys (tm) using your statistic pages to increase their google ranking.. some have discovered this is a good way to play pranks by using google..

Yep, it's just more google-bombing .. Simply hit a lot of blogs that allow Google to index their statistic pages with that phrase as a referer.. and suddenly a whole lot of people wonder why, what where..
It's simple to stop google from indexing your statistic pages.. in your root site directory, add a robots.txt file with something like this in it..

          User-agent: *

          Disallow: /stats/

Where /stats/ is the location of your statistic pages.

[Matt pointed out that search phrase to me.]
