On Agora, you need a reference link to join. The person whose link you used gets a small percentage of every amount of bitcoins you spend then.
Let's say I buy a vendor account for .6 BTC. Then, with another account, I copy my reference link and make a new account using it.
On my vendor account, I put up a non-real listing for say .5 bitcoins. With the account I just made before, I buy that multiple times. Then the account that I used the reference link for gets a percentage, my vendor account gets the .5 I spend, and I don't lose any money.
What stops me from being able to just keep pocketing bitcoins like this?
That would only make sense if agora was taking a commission and giving you a percentage if that commission so you would still lose money
