Assuming you didn't alter the transcripts (which I have no reason to believe you did), this is all kinds of bullshit on Simu's part.
So, wait, all this time there was a loot cap but Reim was exempt from this loot cap? Holy shit. Man those people in the Hand of Reim or whatever it's called truly are the favored sons aren't they.
This doesn't even make sense. If it wasn't possible to pull more silver out of Reim, then how were you pulling more out? Unless there was some sort of secondary loot cap specifically for Reim and you were going beyond that, which sounds like a bug if that's the case.
Again, absolute bullshit. So much shit changes in this game on a constant basis and there is NO easy way to access these changes. I don't even know what is changing until days, weeks, or sometimes months later and I usually hear it second hand from someone here on the PC. Like literally just now I am learning that loot generated in Reim apparently didn't count towards the loot cap, and again just now I am learning that this was changed just 3 weeks ago. But yet somehow someone is supposed to just know that something is a bug that the GMs apparently never got around to fixing, and announced it was a bug and still hadn't fixed it, and that you were not suppose to take advantage of said bug, that you didn't even know was a bug. The GMs should have just personally pulled you aside and explained it was a bug and told you to stop, not start throwing around punishments and saying it's your fault for not keeping up with their ever changing rules.
Wait, was it "over a billion" or "billions" of silvers? I know technically it's the same thing, but saying "over a billion" makes it sound like just a little bit over a billion, where as "billions" makes it sound like multiple billions.
Also assuming you're telling the truth about having 8 accounts and this all took place over a span of 6 months, and you generated at most 2 billion silvers during that time; you could have generated 1.68 billion silvers with those accounts in 6 months just by reaching the monthly loot cap on each account, meaning they are making this huge stink about mechanics abuse and not keeping up with their bug announcements over 54 extra million silvers a month.
I'm all for the GMs maintaining the integrity of the game and I am appreciative of their effort, but this all seems a bit heavy handed based on these emails and the information we have been provided.
