I've been seeing these characters often dressed up like gnomes and they have seemingly scrambled names, not like mine, and all they do is stand completely still and just warp around. They don't do the floating up in the air animation and teleport. Their characters just disappear one after the other. They show up, somehow turn in a quest, all level up at the same time, and then just disappear. Or they'll randomly appear in front of a crystal and synchronize with it and then disappear one after the other without doing the floaty animation. I can only assume that these are automated accounts but it's kind of creepy. Like, why dress up as gnomes of all things? And what's the point of whatever it is that they're doing?

I took some screens here. I don't wanna spam images up in here.
