You are way overthinking this. Also sounds like trying to convince others really desperately.
It was put there to produce content of one type or another even if nothing else just to deny content and income from those trying to anchor on the spot. Nothing too complex or tailored for you personally about it or anything.
The type of content also includes anyone posting or posting on behalf of their friends even if later tries to convince everyone those friends who are absolutely not your alt either don’t mind the situation when based on what you wrote it clearly seems they do.
But anyway wasn’t my plan to get involved in depth just cracked a one liner to sum up why they might do it even if to you it seems pointless. For some ISK is constantly flowing and wasting it is just part of the game and nothing special.
