Yes these afkers seems to be almost in every system as far as I can tell. Docked in station for tens of hours and rarely undocking if ever. Them having clean killboard for countless years suggest that they don’t.
I suppose that one explanation would be scouting, but being out in space cloaked or how some are doing orbiting gate with highspeed would be much better. And specifically Sivala doesn’t make a sense because the local is permanently shown on Uedama Scout stream.
I even heard an opinion from one salty guy that they are bots added by CCP.
