To be honest you can't judge a "scammer" by there post numbers. Theres plenty of people who are shit at dealing with people and have thousands of posts. - Rather than focus on stopping the "seller" why not focus on informing the buyer. It's very obvious if someone is intending to send the items, like me for instance with my Pashley. It was my first sale, but Matthew knew from day one that the bike was as described and had been sent straight away. By the well formed sentences, correct spellings and general professional-ness. And also, instead of giving them some comical red banner that says "Scammer", why not just ban the cuntz ? Forever.
