Are there any tech wizards here that can explain how moneromarket.io works? What kind of database setup do they use? How do they manage user accounts? I'd like to tinker with a monero like ecommerce type site of my own for fun but I'm not really a backend wiz and I learn JS as I go. I have ideas and like to write down thoughts about them but technical skills that would need work. Also how does the legality of that site work? Granted they aren't letting people sell fentanyl or weed there but its basically an ebay using cryptocurrency yet they don't get shut down.
