I certainly wouldn't consider myself a large seller...I've sold 6 or 7 bikes and a few parts this year...and I do relist every other day until the stuff sells. I see nothing wrong with it as it is in line with Craigslist's Ts and Cs. More of the spam in our craigslist is caused by the incessant arguing about whether or not a certain seller is over charging than from actual over posting.
