I think this is a pretty fair assessment of the situation... but I think it's pretty clear he needs to invest in more support resources, because even with all of the panicky "noise" that probably takes up 99% of his inbox, 1% are valid (of course I made these percentages up) and are, for the most part, not getting responses.
Plus, I think he's making questionable decisions like having another sale (which appears to be having the same multiple orders to one BTC address issue) in the midst of legit service issues.
IMO, I would have suspended new orders made 100% sure the back-end stuff was fixed, previous week payout issues resolved and then opened up ordering again...
I also hope if there are still issues after this batch of payments, that he does the above and also resolve payments before worrying about escrow and even multiplication.
