Why am I required to buy something on BrickLink before I am allowed to sell? Why does BrickLink require you to purchase something before you are able to sell? I already have too many Lego bricks and I'm trying to get rid of a lot of them, so I'm not trying to buy more. I'm just trying to sell all the characters I have, but it won't let me.

Why is this policy in place?
It’s not perfect, but it’s their way of finding reputable sellers. Any purchase counts so you can just buy 5 more cheap minifigs.
