As an ex-scammer myself, except not in adult games but on dating platforms, I can surely speculate that a huge amount of people who give money through patreon/other subscription platform are actual subhumans (I'm not even exaggerating) without any life experience, dignity and self-respect. They're just happy with whatever and believe any bullshit devs pull just to stretch game development to laughable lengths, minimizing working efforts and maximizing milking. Just reply in patreon/discord to some hesitant sub with a few nice words and false promises, and it will be enough for him to throw money at you for years before he starts asking questions again. For me, somehow, scamming in the adult game industry looks even easier than on dating platforms, where I actually had to put in effort to persuade losers to give me money 
There is a saying, "You deserve what you tolerate" that fits here very well. For years after adult games industry got established, scammers pushed the line to see how much people would tolerate before they began to lose money, and on example of this game, we can see that you can even spit them in the face with "remasters" and subhumans still can be pushed lower to the new bottom without visible hurt to cash flow to "developers" pockets)
