Bibliogram does not allow you to anonymously post, like, comment, follow, or view private profiles. It does not preserve deleted posts.
All of Bibliogram's code uses the AGPL 3.0 license. In short, this means that if you make any modifications to the code and then publish the result (e.g. by hosting the result on a webserver), you must publicly distribute your changes and declare that they also use AGPL 3.0.
