Anonymity in the world is good and the bad side, so to prevent the bad side are the scammers, who are not honest when posting your product you will do? Because when I posted a sale, the buyer did not trust me. Or I go shopping I can hardly believe the seller will deliver to me just like what he advertised
Hello and welcome:). Yes, anonymity has good and bad sides but anonymity is an option, we plan to have option to make user profile where buyer and sellers can rate each other so there will be security in that sense. We didnt want to not to include option to stay anonymus as classifieds are in majority anonymus, it will be up to user to decide, but even if he stays anonymus we see security in smart contract as the seller wont recieve coins until he sold product as promised

Yeah, protecting both the seller and the buyer is essential on a classified website. I think you should have a challenging or training process so that the seller has a valid travel card / certificate to qualify for the trust. And limit the swarms with multiple clone accounts
