Just had this thought maybe there could be something on the forum where when you sell and item the buyer has to fill out feedback. or there is an alert or message that gets sent to the buyer to help get feedback to sellers to help with the scamming issue. If there was a way that forced or alerted buyers that they could leave feedback might help people leave feedback. I find it weird to ask people to leave me feedback and i have sold quite a bit of items with no issues but theres no feedback left. I myself will be honest and haven't left tons of feedback for everything i bought due to being busy or just plain forgetting if i had an alert in my inbox where maybe i could just reply to a pm or click a link that had a few questions that would be nice.
