this is the exact same problem I had with bisq. it helps to reduce the number of times you have to interact with a CEX or KYC yourself, but it doesn't completely eliminate it. you may still have to do it at least once.

what I am still trying to wrap my head around is, on localmonero and even localbitcoins it was possible for a person to buy coins without already having them. there were always some sellers who would let you send maybe a hundred bux even if you had no account history or anything, and there was never a deposit or collateral.

 someone told me that bisq and haveno can't have this because then people will just initiate orders they have no desire to fulfill, as a form of spam attack that locks the seller's coins for a time, and that this is insurmountable without making the security deposit mandatory. but if localbitcoins and localmonero ran fine for years without this being a breaking problem, why isn't it possible on bisq and haveno? and why can't there be some other way to prevent spam like forcing the user to submit shares to a mining pool to prove that they are earnest? proof of work was invented to prevent spam.
