The Whitelabel template generator allows you to hide avatars for all comments, all official posts (administrators, developers, writers, moderators, editors, moderated writers, and guest writers), and all social network posts. For example, if you select to not show avatars for social networks, all posts that come in from Twitter, Facebook, etc. will appear without avatars.
