IIRC this place was “frowned upon” for the sheer amount of loot people were collecting while idling AFK. By frowned upon I mean, it worked so well it was causing complaints about game balance and cheating 
Re-open it in the current situation and people are like “dude it isn’t even 100% AFK”.
This is one of the oldest, and definitely most effective, mob farms in the game.
