My company owns and operates a popular Q&A site in the UK Often the questions and answers posted by members contain links to external sites. All of these links are automatically nofollow'd.
Since Google introduced their disavow tool, we've been increasingly receiving requests and even threats to remove perfectly good links which, even if they weren't perfectly good, are nofollow'd as they're UGC and we don't have the manpower to vet every link. Here is an example of a threatening one:
Dear Webmaster,On Behalf of [removed.com], I write to notify you that your website has been spammed by unauthorised persons which have a negative impact from your site being indexed on Google.We have found that there are links to [removed.com] in your website [removed.co.uk]. [removed company] is the owner of exclusive rights protected under copyright law and other intellectual property right in [removed.com].Linking from: [removed.co.uk][removed company] requests that you act expeditiously to remove or disable access or delete the webpage/section/forum. I am sure in doing so you will also be benefited from having a clean non-spammed website.If we don’t hear from you we may be forced to contact your ISP and report Google to consider your site as spam website.Here is how we can report about spam sites[removed.co.uk/url]Sincerely,[removed personal name][removed "seo" company name]
What a waste of everyone's time this is!
For the most part, we suspect we're being contacted by naive people who don't understand the difference between a good link and a bad link.
However, sometimes we suspect that we're actually being contacted by competitors of the sites we're linking too, who are using the fuddy disavow situation to remove perfectly good links to their competitors' sites. Just thought you all should be aware of this ...
