Arguing otherwise simply justifies using the rules as a sledgehammer to silence voices you don't like. The WH Press Secretary is a very, very loud voice that should be listened to whether you like it or not. She said nothing mean, nothing cruel, nothing divisive or illegal or inciting violence, she linked to a news story by the 4th largest publication in the US. This is about as vanilla as you can get and it is completely unjustifiable to block her account just for that.
