So I actually don't mind his posting there. Obviously, there is an element to this where he probably could and should be finding you town, but from his perspective, he doesn't really want to reward something he sees as cheesy/cheap play, so he resists it. And he did accuse you of avoiding talking about Polar, to which you basically admitted to not having anything to say about him. Logically his position tracks there. I think you've perhaps felt the pressure more than you needed to, but if you consider that Ultra thinks Polar is scum, finds your lack of interest in that direction something to mention, and then resists giving you an easy read out of his ethos, I think his posting sequence can be understood. He also never really seems invested in moving away from Polar.
That's my two pence on it, anyway.
