This feature works much like the American movie-rating system. You can select G, PG, R, and X ratings for the avatars that appear on your site. If your site is family-friendly, you probably don’t want it to display R- or X-rated avatars, so select G or PG.
Select the radio button for a default avatar next to the Default Avatar option.
Avatars appear in a couple of places:
The Comments page on the Dashboard: The first two comments display either the commenter’s avatar or the default avatar if the commenter hasn’t created his or her own.
The comments on individual blog posts in your blog: Comments displayed on your website show the users’ avatars. If a user doesn’t have an avatar assigned, the default avatar appears.
To enable the display of avatars in comments on your blog, the Comments template (comments.php) in your active theme has to contain the code to display them.
Click the Save Changes button after you set all your options on the Discussion Settings page to make the changes take effect.
