Misinformation is Sneaking in to Linkedin
There is an Easy Solution
If you post an article, and someone makes a spammy comment, if its really bad you can Delete it - but Hiding it is better. When you Hide a comment on Faceobook, no one sees it - except the person who made the comment. That means they are unaware it was hidden. This helps everyone, it makes a discussion more civil, and there is no angry backlash from the comment author.
I would love to see Linkedin add a Hiding feature People who post articles need this, and there might even be more senior people posting if they know they can control the comment flow in a more flexible manner.
