He is talking specifically about sellers who have gone through an extensive KYC process. Those sellers identified as verified have connected a few account with Keybase, provided their real phone number, and provided their local government photo ID. We also do a check with the seller via webcam.
It is a very nice process to identify and fight scamming on transactions and business that deals with decentralized and anonymous. Telegram has turned to the home of scam. I do receive ton of messages in my telegram account daily and sometimes after much verification, I do discover that those projects are completely scammed. Scamming will reduce if we began to ask people to do KYC before doing business with them.
I am for privacy and that is what bitcoin was created for. Making transactions without KYC or third party knowledge! However, because of the scamming, that is going on that has changed.
Sure of course, everyone has the option to deal anonymously, and we also can offer escrow for that if you choose, but most have really embraced the new system we created, and all the active sellers have become verified now, so it has been working very well. No system is perfect but it has reduced scamming considerably.
