LINKSPAMMED MY SITE WITH A LINK ADVERTISING THEIR WEBSITE "Hi, I manage the online presence for Banner4sale, at http://www.banner4sale.com/ and I am writing to seek out your help. We have recently been contacted by Google regarding some of the links back to our website, and we would like your help in getting some removed that we believe may be negatively affecting our website. On your website, the following links currently point back to our client’s website: xxxxxx Please kindly help us by removing/taking down these links. Once completed, can you please kindly confirm with us you have done so? In cases where we do not hear back from webmaster’s we plan to include the links/root domain’s we believe are problematic in our Disavow File, and we’d like to not have to include yours. Thank you very much. Best regards,"
