Here we go again. Instead of apologizing for your mistake and removing the advertising you are hiding behind a google loophole to justify the use of our trademark. If you really did not intend to deceive the searcher than you should have never used our trademark term to begin with.

So? If the keyword is a competitor's brand, this is clearly deceptive.

I'm not sure what your point is in the above, but looking at the blog you seem to think that giving a name to the mechanism by which you have engaged in deceptive practices absolves you from responsibility. It does not.
