Hi everyone
Just so that I understand you all correctly, this list of negative
keywords is not something that Webmaster Tools would provide, but
rather something that you would provide, is that correct? I think
that's an interesting idea, but I'm not sure if it would be something
that would be feasible.

Are you currently having trouble that your site is showing up for
searches where you don't want to be found? If so, it would be great if
you could start a thread in the crawling, indexing & ranking sub-group
here so that we could look at it!
