I just found an emo bear (seems to be fully-outfitted) in Nandak Intention. Seems that it was hidden/lost in the bottom right alcove (key spawn place) due to the drop-a-bear-and-it-flies bug.
People were (are?) leaving them because there was (still is?) a bug that made the bears huge and floaty. There were bear parties going on. See i.e. Varaeth's photo.
Think of it as a form of voluntary wealth distribution. Trickle down bear economics. Glitchen are donating their bears to the greater good of other Glitchen walking in to see GIANT FLOATING BEARS.
(I planned to leave the bear there, walked away a few streets, felt sorry for the poor thing, ran back and saved it. So yeah, I only drop them for snapshots and then pick them back up. I can't just leave them hanging in mid-air. =P)
