12. Do not "bump" your sale threads with the word "bump" or no relevant information. All replies to your own threads in sales MUST contain information pertaining to the sale. You must have a minimum price reduction of 10% to post a price reduction as a bump. Otherwise, edit the original post and do not bump! Do not use sneaky bump tactics like "If you PM me, post in the thread that you PM'd me". No "PM sent" replies to threads. There are too many bump tactics to list, so please just don't try any of them. Trading bumps is not permitted, you bump for me, I bump for you, etc., so even if there's no harm intended, do not bump others' threads because you think it's a good deal, or the recipient will feel obligated to bump your thread, and you can see where this will lead.
