I think making buyers ratings public would be nothing less than a major security step for sellers.
If you could have it so you could see the rating on more than just ACTUAL sales, that would save sellers a lot of time aswel.
Say some sort of format like.
Buyers name: @blablabla
Buyers location: united kingdom - (so you can say from the beginning whether you can send there or not.)
Sales rating: 3/5 (how easy is it to do business with this person)
Response rating: 1/5 ( if they inquire to buy a animal but when you respond they dont get back to you, that must be really annoying)
How many times they viewed the animal they want to buy: 2 (this could be a great indication of how serious they are. More views means they have thought it out properly. 1 view and it’s likely a scam)
Community trust level: 1/5 (if a buyer is active in the community then your likely to see your animal grow through pictures and posts. You will know what their husbandry is like and how they treat their animals.) (It’s not just about finding a great breeder, breeders need to make sure they are selling to responsible buyers)
From looking at @blablabla’s buyer profile, I wouldn’t be in a rush to do business with them.
Disclaimer: I used @blablabla because it didn’t exist yet, but it’s likely who ever makes a account with that name is making a throwaway account anyway.
