Currently, we have a nice and simple obfuscation logic, for obfuscating a user's display name with a given value (supporting tokens). This was mainly implemented to lower the amount of email leakage through the "email_registration_username" submodule (which syncs your mail address with your username).
In certain situations, it might be a good idea to also have this functionality in the main module (e.g. to not show "Created by admin_1" on nodes).
Move obfuscation logic of submodule into main module
