I am surprised that free-DC - knowing the reason - DELETES user data from their statistics if the latest export does not include that user.
DELETION requires much more activity than stagnation.
Maybe their reason is to draw attention to the situation?
But if you access free-DC, you receive the announcement anyway - there's no justification for deletion.
When Universe-users - or other-users in a similar situation - authorise export, free-dc needs to re-establish the user, which costs more activity.
Free-DC could easily be smarter.
