During the past almost three years of doing YouTube videos I had no hesitation calling out those who sold forgeries and I would have no problem calling out deadbeat bidders either.
Lately, I have also been hit with numerous deadbeat bidders (and those who didn't ship me the item after I paid for it) and all of them wanted me to "Cancel The Transaction." If both the buyer and seller mutually agree to "Cancel The Transaction" then the buyer does not get hit with a "Strike." I refuse to allow buyers to wiggle out of a transaction that easily.
The fact that sellers cannot leave "negative" feedback to buyers is ludicrous.
My favorite guy on YouTube is a guy called "Crazeenydriver" who continually rips Ebay and deadbeat buyers on video. Below are a few links to some of his videos:
