> covering over 100 sites (including Yelp, Yahoo! Local, and more)
I wish that, long ago, I'd registered More as a company and trade name. :(
> Provides email marketing
Sadly, yahoo is already one of the bigger single spam sources. I really hope they do not intend to provide the actual email lists as well.
My other concern is: will they be selling our web site content to their customers? And if so will it be from yahoo (whose scrapers we can block) or bingbot, which we probably should not block.
