With that came another question:
How does the forum deal with a person's right to be "forgotten"? Imagine that a user wants to delete all his activity from the forum, is it possible?
There is no such function on the forum. A user can delete all posts and topics created by him/herself and block himself/herself with a secret question. But. Deleting everything a user has written on the forum won't do any work, because we have tracking services that save everything that is written on the forum.
