Place a Feedback Link on each article to report misleading and false information
When comments were on all articles, false information was called out. Now without comments, articles are published frequently with misleading and false information. Your employees, when occasionally engaging the comments, state that Yahoo strives to keep false information and misleading information out. The comment policy also states this. So give a feedback that links to that article to report articles with false and misleading information to Yahoo. No one other than Yahoo needs to see it, so it won't be offensive to others and it won't start comment storms.
