Haven't seen any either, but second life is where I first learned of metrobay, after unknowingly stumbling into what appeared to be a lair for or shrine too the H.E.R. drones deep below the coghaven Sim that was thankfully vacant at the time and asking around what a H.E.R. drone was, thinking it was a new kind of avatar only to be told it was a reference to world of metrobay. Never had courage to go back and see if it was still there.
I'm told though that several metrobay heroines secretly roam second life keeping it safe.
