Anonymous users skip comment approval but they shouldn't 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
On my side, the problem was the use of the cleantalk module.

In this module, in the configuration page: admin/config/content/cleantalk/settings

You must uncheck "Enable automoderation" if you do not want to override the "Skip comment approval" permission
