Posts with close votes aren't supposed to be tweeted.
The @StackWorkplace feed just shared the post Why not always feel confident enough to speak and share my views in workplace which had 3 closevotes (and a flag). I got to the Tweet 2 minutes after it was posted so I really don't think all the votes were added after the tweet, especially since one comment states "I voted to close" 3 hours before the tweet.
I also suspect this (now deleted) post was tweeted after getting close votes: Computer Science minor? which I closed/deleted about an hour after it was tweeted, it also had close votes when I got to it.
The Twitter bot seems to be ignoring the check for close votes before tweeting questions.
