I can’t seem to find information on it. It seems like it has to do with account age. There are blue, green, orange and red circles, what do they mean?
Also why do different accounts look different or some accounts female and some look male? Is it just to see which orders are by the same maker?
I am not sure, think the avatar you get is just random.
The color’s of your avatar change depending on the type of payment method you make/take the offer with.
Avatar is random.
Red are unsigned accounts.
Blue, signed since less than 30 days.
Green are signed accounts or signing not required.
What are accounts that don’t require signing?
