I had overture or whatever they call it now set to not subscribe to there content network. Without warning all of a sudden I started seeing scraper sites using yahoo ad content appearring SERPS using my adverts in there content from yahoo. So I told yahoo to go away permanantly.
I've got an idea. How about they honor the wishes of the advertiser? If an advertiser is simply not interested in having their ads appear anywhere but on search engines, don't create contractual loopholes and mandatory "Domain Match" programs that force them to emblazon their company name and identity on scraper sites and typosquatter parking pages. Sound like a solution?
