Would you like feedback from a buyer who wasn't really happy with the item but didn't think it worth complaining since it wasn't expensive? So they decided not to leave any feedback at all.

What do you think they might leave if they were told they had to leave feedback?

Sellers can't leave negative feedback for buyers. So you think they should be forced to leave positive feedback for someone who took ages to pay and responded with rude messages?

Have you really thought this through?
