Even in Steam, sometimes there are stooges who do their job with the heel of their left foot.

Good luck returning to Steam!

How's hard to change those characters which Steam disapproved? I meant, I would like to suggest to make a thing like "some other indie devs does" - create an altered version of the game which Steam will approve AND create a patch which brings back the original content, BUT it will be uploaded here on somewhere else, outside the Steam.

I know this is a bit late, but you can always sell it here on Itch by making it a Paid project with your listed minimum price to access the content

Sad to hear this, as BlackKnight82 mentioned they kinda are definitive, as alternatives to steam there might be(itch not included as we are already here) gog, jastusa, kagura store, might be more that i am unaware of, but i'm not sure about contract, and visibility and how many people buy there

Unfortunately there are very few chances from what I have understand. Steam is worst with devs that the justice is with criminals... they have appeal. Steam.... basically doesn't.

and the policy of steam is very very weirs with nobody really knows what the rules are. From what I have understand depends who will review your game (i understand there's somebody named Mary who likes to ban AVN for whatever reason)

also in many cases they don't tell you what's the problem. and you can't "fix" the issue once is banned. I haven't put anything on steam, but that's what I have heard. But It's weird that the demo passed, but the game didn't. the ether change the reviewer of the game contains something weird? From what I know only realism or pedophilia are reasons for banning. And pedophilia is "looking to young even if you say it's 18 yo+" So even the graphic style might be and issue. It would be easier if those idiots talked but here we are...  Some reviewers seam to want to ban a game and they just look for reasons. That's the biggest issue with steam from what I have heard.

Anyway I really hope you can unban your game, but i doubt that it's possible. 
You should think of alternatives: patreon (hate them but...), subscribestar, the guy that makes Fetish Locator has a store, etc. itch.io is not known enough unfortunately.
I wish you the best of luck and don't forget to announce on f95 what you have decided.

PS: If by a miracle, the game gets unbanned, will the people who buy the game here get a steam key? 10x

Saw your game had disappeared from my Steam wishlist and assumed something along these general lines had transpired. Still looking forward to the full release and hopefully you can prevail on your appeal with Steam for the wider market access.

First off, let me say the demo was amazing, and i'm sure the full game will even better.

I hope you find a solution to the steam problem, and it would be cool if you released on itch.io in the meantime!

I've  heard steam is doing this a lot, and what's more annoying is they normally refuse to look into it any further if they come to that conclusion.

I'm assuming they came to that conclusion because of the scene where Margret was at school with the MC, unfortunately steam doesn't care if its college or just school themed with adults they refuse to have any depictions of a school in nsfw games on their store, which i get but even if you choose to alter the scene or remove it out right they wont change their mind. 

Its a crappy situation but i hope you're able to sort something out, i was looking forward to the release of this game.

I am sorry to read that, your game is so gorgeus, I am unable to see what's wrong with.

I want to wish you good luck.
