Feedback (specifying eBay but applicable to other marketplaces, too) should be published by default as positive unless a buyer/seller either opts out of leaving feedback or specifies negative feedback

Online marketplaces (like eBay) should mark all "ungiven" feedback as positive unless the buyer specifically opts-out of giving feedback (which must be selected on each order) or, obviously, leaves negative feedback. The current system punishes good sellers just for selling their items to buyers who can't be bothered to click through two forms on an email.

People are very quick to leave feedback when something goes wrong but rarely go out of their way to write a review when the order is fulfilled just as expected, this artificially inflates negative feedback. The feedback system I'm suggesting would counter this effect.

An order where nothing goes wrong is a "good" order! If an item you ordered arrives exactly as you expected, when you expected, etc., then the seller should receive positive feedback on their end, yet people rarely do so because they consider that the bare minimum. Counterpoint: Maybe so, but what's the "above and beyond" in that situation? The reality is that marketplaces require sellers to have positive ratings in order to succeed.
