In my drupal 8.6.1 news blog anonymous users can skip comment approval althouth permissions are set to not skip. I rebuilt the permissions but nothing changed.
Also in comments page I see that some anonymous users are linked to an anonymous user account with id = 0 !
My site is not hacked and I can't understand what is going on.
Check this image!
Is there a chance that my drupal 8.6.1 has this unexpected behavior because is running on server with php 5.6?
Thanks in advance
