It was, but the offer was never .0017, that was the bid at times during the day.

Okay, I'm repeating myself here, but, MM's have no obligation to fill any buy order at the bid nor any sell order on the offer.

On regular markets using the market maker system, Naz and OTC BB, you can often get buy fills on the bid and sell fills on the offer. The buy fills on the bid are usually just blind luck when an MM matches your buy with an equal sized sell at the same price. He makes nothing on the spread, but he does get the order flow commission often in hopes of getting further orders directed at him from whatever broker you use.

Again, on regular markets, especially when there is a ton of volume coming, MM's will happily fill your sell on the offer, going short if they don't have inventory, knowing that they can sell the stock they just bought from you higher in a few minutes or even seconds.

Best we have is Level 2 quotes which while it shows size, doesn't show true size or depth. They have Level 3 platforms or things like PLINK that show them all orders and depth.

PAIM is an "unsolicted only" Pink Sheet. That means, assuming the MM's follow the rules, that they can only quote for bona fide customers that are not other broker/dealers and they cannot trade their own account, long or short. They are supposed to only match up buy orders with sell orders. They pocket any spread between them plus any order flow bucks.
