I think we've lost sight of how we can fight back. Here are the links to the petitions. PLEASE SIGN!

Tell MasterCard, Visa & Activist Groups: Stop Controlling What We Can Watch, Read, or Play https://chng.it/b2pMbsLvdg

Mastercard: Sex work is work. End your unjust policy https://action.aclu.org/petition/mastercard-sex-work-work-end-your-unjust-policy

Call Payment processors and take as much time as possible (This is the solution).

The reason phone call complaints are effective with these payment processor companies is because it takes up valuable time that the company could be otherwise dealing with other issues.  Phone support is expensive and slow, which makes it an ideal pressure point  A large public outcry is what causes companies to pay attention and consider backtracking.

Make a script about why this is bad (payment processor companies shouldn't be censoring legal material because they personally think it's immoral and it's an attack on free speech - you can ask AI to create a script for you if you don't have to time to write a long message) then call VISA/MasterCard/STRIPE/Paypal, you'll be on hold for a while because everyone is calling, and say you'd like to lodge a complaint.  Then when they ask what this is in regards to, just start reading your script.  The longer the better since that's the point.  We essentially have to keep this up for the next few weeks if we want something to happen.  We don’t need to be aggressive - just persistent. Keep the pressure on and call every few days, or every day if you care about this issue.

Service reps will now try to quickly escort you to "e-mailing" instead once they realize you're complaining about itch and Steam's recent censorship - try to just keep them on the line.  In one call when they attempted to do this, I simply asked, "Are phone call complaints reported to your company or not?" and they just kept repeating "You must e-mail _________" - I was like, "You're not answering my questions, do you report them or not?" and eventually they transferred me to a supervisor who was really awesome to talk to and spent a long time talking to me..  Asking them about why companies are attempting to ban legal content is also a good question that they can't answer but will keep them on the line for a while.

Itch is mostly to blame. They bent the knee. There's are multiple ways around things. It takes time, yes. However, they could have easily said that they were looking into alternatives and would not delist games. Now, not only are they losing game developers and customers but people won't trust them again. Even if people find it annoying to host on another site, they will do it. Itch isn't like Steam. There are plenty of other sites people can host their games. The payment processors will back track eventually. It has nothing to do with the type of games. It's the censorship. If people think they are going to stop at NSFW games, they are wrong. It's already going past that.  Visa and Steam has already been bombarded by calls and emails so much that their support staff is overwhelmed. When things do get backtracked, it won't matter for Itch. The damage is done. Steam will be fine. Itch won't recover.  Hope it was worth it.

Itch is bad and evil. Fuck you itch

Don't blame this on "Payment provider"/"Payment Facilitator, simply get a new PF if the current PF creates problems. Mastercard and Visa are bad but as far as I know are only trying to enforce USA style "child porn" laws on foreign countries (yes they are that bad). MC and Visa have not banned adult contents, this is an issue with the current PF, see GBPP (Global Bran Protection Program or such), BRAM (Brand Recognition ...)  programs by Visa/MV to see what MC and Visa officially currently accepts. What MC/Visa accepts if more or less -> local law - CP unless CP ban breaks local law (probably). 

Finding a new PF should fix the issue, and there should be many PFs out there that do adult contents, especially contents not featuring actual real people like drawn images. I can try to see if I can find a PF to give ITCH a call but this situation is the fault of ITCH not finding an alternative PF, and mostly not the fault of MC/Visa.

That being said there is a lot of unofficial rules implemented by PFs  but those should be possible to navigate by ITCH.

Love seeing all of this after it got revealed that itch in fact could have switched payment processors at any time and chose not to until now.

If Itch is reading this, what about creating a separate company and website with the same code as itch.io where only cripto is accepted as a payment method? Then everybody that hates Visa and Mastercard (both customers and creators) could just move there.

Adul content is still exist in here! It's probably nothing to do with adult content , othervise it coud have been a very easy process, an  official statement or something to inform the creators and customers. Age restrict the content and/or the accounts.
How is that openly adult sites (like PHub or marketplaces can handle payment) and not blocked by the proceessors?
In the end of the day somehow the money is going into one direction here, only the payouts have been blocked by the processors??? It is probably good enough for a customer but the money does not reach the (adult or not) creators.
