For Region admins there is an urgent need for bulk Actions (repeater Status change, Delete) for selected repeaters in Repeater List. Some additional build-in filters for repeaters with 0, 0 location and Out-of-Boundry would also be very welcome.

I would argue not really as that is Nicklas referring to pings which is around to long and this is about repeaters and observers still in the list after a long time
