If a user doesn’t add their own avatar, sites often provide a default, so that there’s at least something to see. For a long time on Coub, we used a human silhouette against a grey background. Some sites or apps generate random avatars, so that each one is slightly different. Recently we made all avatars circular, and the default image didn’t look too good in that format. So we decided to make new defaults (and not just one).
