There was a nice little article in Valleywag yesterday showing that Doubleclick is buying AdBrite's trademark term as a keyword, and including the competitor's trademark in the ad. That's pretty much the most blatantly illegal think that you can do in paid search, and Doubleclick - supposedly one of the biggest SEM firms out there - is the one committing the crime.

Doesn't his make you wonder about their integrity as both an SEM firm and affiliate network? What other nonsense are they up to?
