Should I block this ad?

Ad links to search page

[farmboy]

I noticed a new ad appearing on one of my pages, got the URL and went to the site. The site appears to be just a search engine with a plain layout very similar to Google. There was nothing on the page about the topic of the ad. Apparently, the only way to get the information would be to conduct a search using the search engine.

I conducted a search and it lead to a typical MFA page with nothing but ads and "similar searches" links.

The subject of the ad/keyword that appeard on my site is not some obscure topic. Over at overture, the top 5 bids for the term are all over $3.

If one of my visitors clicks on the link, he/she will end up at a search engine. On one hand, it may annoy my visitors and cause them to be hesitant to click ads in the future. On the other hand, if the owner of this site is willing to pay for this - why not keep it?

What would you do?

Personally I block all these types, as they provide no content, and so are basically feeding off the back of search engines, without the work involved.
I also block "best'number such as 3'" type sites, as they do much the same.
