Allow hiding user profile / activity
Please provide a way for users to hide their profile (or only the public activity part of it, if they prefer).
Displaying Activity / Most Recent Activity is in no way essential to providing the service of hosting git repositories. The same goes for the whole profile - public projects themselves are accessible other ways.
Bitbucket, surprisingly, allows private profiles.
Maybe a bit far fetch, but I think this is related to GDPR as well, because users don't explicitly consent to processing of activity data, and that data is not necessary for providing the service. Article 7 (4):
When assessing whether consent is freely given, utmost account shall be taken of whether, inter alia, the performance of a contract, including the provision of a service, is conditional on consent to the processing of personal data that is not necessary for the performance of that contract.
