A BST rule about bumping. Should there be one?

[Luke]

If the seller isn't adding dropping prices, I think one time after 7 days is enough. Then if it hasn't sold and they want to bump it every few months, that seems fine.

Items don't all of a sudden sell after the 7th bump at the same price (or with a tiny price drop).

It's a very small % of members (and really only one comes to mind right now) that clutter up the BST with over-priced threads and bumping them every few days. I would love to see a rule or guideline that makes that go away. Can you imagine if everyone posted a $30 T206 at $150 and bumped it every 3 days? The BST would be unbearable. The fact that only a few people do this shows that the overwhelming majority of members are courteous, but a rule to make the 1% stop would probably be very welcome.
