Generally speaking markets rely on supply and demand. The market cannot be affected by bumping a thread 40 times in the for sale section. One would suggest after bumping it 5 times your product is not in demand. Usually this is down to price. In fact it is always down to price. When a potential purchaser says "I don't like the look of that mark" what they are really saying is "your product is blemished and I would like it cheaper. Yet today I see for sale threads with multiple bumps. Taken the hint. You wouldn't get told no to a date 7 times and keep bumping into the birds boobies in the hope she miraculously finds your good self attractive all of a sudden. Selling your fine wares is no different. This was free advice to aid you from someone with a sales background.
