I have an idea for a marketplace free from government intervention for my region. I believe some moderation is necessary to prevent fraudulent sellers and buyers from ruining the business and to avoid the sale of undesirable products.

If the marketplace is local I would even consider basing it on a chat protocol, like Matrix. Websites can be taken down easily.
Are you using any escrow system in your Marketplace?
I'm not handling any payments. It's just a directory. Buyers contact sellers directly and everything else happens behind the scenes. I don't even log it. It's just an email form to contact the seller directly. Or they can use their email client or sometimes the seller has an online store and the buyers don't even have to use email. It's really P2P.
