Here are those tweets:
Those links have zero value. It's a waste of time if you're just doing it for the links.

Now, this is not new. Google has been saying this for years, most recently in June that not only are these links not of value, you need to nofollow them. I mean, Google has been saying it is dead for links since 2014 but some things won't die.
