We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Participated projects visible for all on user profile
If I write a comment on platform meinBerlin and take part in a participation process, everyone can see my profile and in which participation process I took part, even I'm not logged in. It's not anonymous enough.

--- END ISSUE ---
