In my humble opinion not allowing sellers to bump under certain circumstances, such as adding new items, will lead to more threads being started versus consolidation. Production Knives for Sale by Individuals would be a prime place for this to occurr. A thread can end up on page 3, 4 or even deeper by the end of a weekend day and if the seller wanted to add a knife he would start a new thread to get exposure for the new item rather than risk it not being seen until Tuesday or Wednesday. According to the rules a seller could end up with 4 threads on the first 2 pages instead of 1. This change also seems to promote buddy bumping for lack of a better term. There is no question here, only a comment, no response personally needed.
