Woke up this morning to see that Kaos has apparently passed on his membership. I guess others took a more hard-line approach to this than I did. It's just as well. He violates the VN TOS almost daily, yet remains oblivious to that fact.
Based on a prior personal request/favor from Thistle, I've agreed to leave him alone, as she's explained to me that he has a history of these obsessions, and I'm honoring her request. I can't say it's a gratifying result, but I'm also very happy to not have to step away from the alliance.
