I've been getting to many of these emails:
My name is John Doe web manager of www.somewebsite. This is our 3rd and final request to you to remove links from your website to ours. If we don't succeed in having this actioned we are left with no choice but to DISAVOW links from your site to ours via Google's Webmaster Tools platform and also at the same time advise Google of this in our reconsideration request to them. As I am sure you are aware this could potentially be detrimental to your website which we do not want to happen.
Because I have a lot of user generated content, I really can't handle such requests (too time consuming). Can this potentially hurt my rankings? Should I pay special attention to take care of these requests?
