I would like to have the opportunity to actually "maintain" my profile's wall:
At this point I can only delete posts made by other users or myself. Posts made by the system itself cannot be deleted and tend to flood my wall.
Therefore I would like to have the opportunity to be able to delete all content on my wall.
If this is not possible, it would be nice to at least shorten the system's posts to one or two lines only.
(I attached pictures which show the problem.)
Deleting comments made by oneself or other users is possible:
Posts made by the system are large and cannot be deleted --> wall is flooded.
