I heard that Twitter was not allowing you to share a link to a news story on the NY Post.
This is the link they will not let you post:
https://nypost.com/2020/10/14/email-reveals-how-hunter-biden-introduced-ukrainian-biz-man-to-dad/
When I tried to post it, I got this message:
“We can’t complete this request because this link has been identified by Twitter or our partners as being potentially harmful.”
