So who gets to decide the punishment and under what authority? Patrick? You? Someone "objective"? theymos?
Apart from Phin publicly apologising, what is it that you want as a resolution here and from whom? Based on past experience, a significant proportion of the board likely has Phin on ignore and an even larger proportion regards his statements with extreme skepticism (things we know for a fact bother Phin).
If you want theymos to ban Phin, then you need to take your arguments in favour of that to theymos.
If you want the community to shun Phin, then I'd argue that for the most part they've been doing so for a long time. We know that from the time when the extent to which people were ignored was visible and Phin's level of being ignored would go through the roof when he was on a crusading frenzy. I doubt you'll find many people reading Phin's threads hoping to discover the truth about Bitcoin's latest drama - they're way too exhausting to read, too "theatrical" in nature, and full of too much tenuous "evidence" for that.
If you want Patrick to take action against Phin, then you need to talk to Patrick about that.
In a way, the ultimate punishment is the one Phin has brought upon himself - his credibility as a "crusader for truth" is already so damaged within this community that his claims against Patrick didn't gain any traction. Phin wants to be viewed and acknowledged within this community as someone who has selflessly and tirelessly spent thousands of hours promoting Bitcoin and pursuing the truth. That he he isn't perceived that way is almost entirely the result of his own behaviour rather than attempts by others to discredit him, and everything about the way he handled this situation has only served to further undermine whatever small remnants of credibility he might have retained up until now.
Phin being Phin, that his attempt to blackmail Patrick was more likely to damage his own reputation than Patrick's is something he did not foresee (I'm convinced Phin has a script in his head about how these things are going to play out when he does them and is utterly unable to understand why they don't play out as expected).
