Are you implying Argent has something to do with Captain Flinders? That is how I read it, and I don't care for the implication.
I would speak up no matter who the situation was turned on, I don't know much about Flinders, and what I do see on the OWF, I'm not a huge fan of.
But, let's look at it this way, SOMEONE had him sanctioned, and sentenced to ZI less than 24 hours after he leaves the alliance, for owing 60 million (a figure he disputes) and not resigning in the proper manner. Permi-Zi is my guess, based on the re-roll comment. You (collective YOU, not you inparticular) obviously didn't care about the money, you just wanted to attack him, because he can't pay once sanctioned and lord knows anyone showing him proof of what he owes is beyond the norm. One should always just take whatever the other person says as the gospel truth in determining debts, right?
You put it out here instead of just handling it quietly, like most alliances do. Expect commentary, and if the notorious TGE "justice" system can't handle a little commentary, re-think it.
