I think people are overreacting a bit.
You can critique a developer, but it needs to be constructive to either the developer or to the community. Being open and honest doesn't mean being cruel, but sometimes honesty is painful. Let me give you an example.
I think Crushstation is actually not a scammer, I think he is something worse. I think he is sadly incompetent. Like many developers he seems to have feature creep. He starts with a cool idea and then expands upon it, the problem is that he lacks the ability to do the things he adds. Like the idea of making the game open world in bangkok, which means you need to add in tons of random events. 1) This is a problem since it created GENERIC sex scenes, but also 2) he also seemed to not know how to do it. So he learned how to do it with trial and error and that takes time. Him learning to code isn't fraud... but it does make development slow to a crawl.
His feature creep is all over the place, clothes being a major one. He wanted people to wear different clothes for different events to make it feel more authentic but in the end it clearly was to much work for him. He ended up majorly cutting clothes into a more simplistic form, but what he should have done is just not added new clothes and recycled what he had. He ends up wasting time on these features that don't matter, and making everything look worse.
To be a scam Crushstation has to be intentionally making his game bad, and then pretending on fixing it. Personally I don't see evil intent, just incompetence. If he wanted more money and was unethical, he could have been significantly more greedy in design, like selling save slots LOL. Note he is greedy though by selling perks on patreon, for those who don't know how to edit variables in their browser console. So he isn't a saint...
In the end I think Crushstation has created a monster that he doesn't know how to fix. Clearly this game needs to be more linearly focused around a story, with well written sex scenes, like how the beginning of the game is but quality is hard and he is struggling with it.
In the end, if people think if development is to slow then DON'T DONATE. If enough people stop supporting him he would be forced to change, which can be good or bad. What I can tell you is ranting at him on this message board is pointless. Even if he does read this message board he wouldn't respond back to someone being rude.
