That’s not really an answer to the question of “......Are you forced to open the post?.....”
It’s a couple posts a day and unless you’re on 24/7 it would be very easy to miss them.
And even then, just skip over them.
The rest of us do that when we see something we don’t like.
Barack Obama makes but one speech a day. Should I ignore him?
I rarely see the posts and that is why I joined the ping list.
