Nothing stops that...but if the buyer was saying he got a package it was empty...then obviously the DCN would show delivered and the buyer would agree to that...the buyer is only disputing that the box was empty... I can not tell you how many times a newbie has proposed this question...and the thing the newbie is not taking into account is this...VENDORS ARE NOT HEAR TO SCAM!!!! We make way to much money....to pull of a scam like that...of course it has happened...and if it did it would be noted in the notes...and if another buyer had that problem...they would start looking at the vendor...but that is what the feedback system is for.. and why you should go with a trusted vendor that has been on the road for a while.. But again...realize that vendors are not scammers...you will not get scammed on here if you choose the right vendor...and it is WAY more likely that the buyer is lying...then a vendor. In fact....so YOU KNOW...there are a lot more scam attempts by buyers...then vendors...They can change name in a second...they have nothing to lose... but I have to tell you...in my year+ in all my orders to over 500 different people....I have never had a buyer try to scam me...so that tells you how much scamming is going on. The truth is...there is not much going on ...on either side...bit that is boring to talk about...and for new people...they want to hear everything 100 times before they man up and order. It has ALWAYS been like that...and I assume it will continue And some buyers..dive in head first. But the fact is this...nothing is perfect and anything can be done one time...but in the end...nothing is worth it and people will be honest.
