Segments deleted, but there are still flagged segments

With the recent attempts to ‘clean up’ segments I can understand the deletion of duplicates. However many quite normal and popular segments have just disappeared. And yet there are still flagged segments on my desktop feed. Why aren’t all flagged segments immediately removed in one overnight purge, and any segment not ridden in 5 years [this would remove most bad GPS segments, and old abandoned training route.] Perhaps give people the chance to nominate segments for deletion or renaming rights.
