The real bummer is that buyers are very reluctant to leave negative feedback on eBay for fear that they will get a "retaliatory" negative against their own feedback, left by a dishonest seller. eBay is aware of this and is about to roll out an enhanced feedback system which will allow users to rate sellers on a variety of different dimensions, such as: item described accurately, prompt shipping, packaging quality...etc.
This still won't make dishonest people honest, but at least the scumbags will have to work a bit harder to not get outed.
