But surely you have feedback from other breeders from being a good buyer? And you have this website! While it isn't seller/buyer feedback, it still proves you are a real person with real animals!
I have a trader rating on fauna because people rate me for being a good buyerMaybe you can ask some breeders who you have purchased from in the past if they would leave you some positive feedback.
I guess it just comes down to using your best judgement. If anything seems off, don't do the deal. I understand that everyone starts somewhere, but we also need to be careful who we are dealing with. New names are popping up all the time and while I would like to have faith in these new names, all of these scammers do make me wary of dealing with them.
