Buyer leaves negative feedback without contacting sellers first. Then says he will retract negative feedback if a replacement is sent without sending back the original item. When you send him another item, buyer sends insulting e-mails and will not retract feedback. Check the buyer's "Feedback Left For Others" section. He leaves negative feedback for everyone. Multiple sellers have explained the same experience with him. After contacting many of these sellers I received the same story. He uses negative feedback to get sellers to send him free stuff and then has the nerve to insult you afterwards. I was extremely amicable to Mr. Racer, but that did not matter. He was extremely rude and resorted to name calling out of nowhere. 23 negatives, 1 neutral, and 1 positive out of the last 25 feedback left. 57 negative feedback left for sellers out of 73 total left. The frequency has picked up as I guess he's perfected his scam. All Ebay sellers should block this guy immediately if you don't want a negative feedback. I ended up sending him 3 of the same item that he ordered and refunded him completely and he called me a "douchebag" when I asked nicely if he was still going to agree to feedback revision. BEWARE!!!
