You might have seen "not verified" status in your drupal 8 anonymous comments. It's very indecent to show these comments to users on corporate or any other business related website.
To remove it from comments we just need to change settings in Drupal 8 themes appearance section.
Disabling (not verified) status in anonymous comments in Drupal 8:
Step 1: Login as admin to a website.
Step 2: In 'Manage' section of top admin menu click on 'Appearance'.
