First, you'd have to define how one can determine what an abusive service is. Is Facebook an abusive service? Is some random website that happens to use FB's SDK an abusive service? How does a normie internet user find out the site they are using has abusive code? Some plugin/extension that has a moderated list that prevents a page from loading and instead loads a page dedicated to explain how that specific site is abusive?
