It's even simpler than that, 'Select Tell' > 'Friends only' or a checklist for 'tell in area only' or by level only (the PF has this criteria) would suffice for majority of players. As you've surmised, SE does not have the manpower or capability to keep the current filters updated and as a result, it is not working.
