Recent screwed on parts threads disturbing

Seems like negative parts for sale transactions on this great site are becoming way to frequent. Personally i've yet to have a problem in over 75 buying/selling deals on FABO. What is most disturbing to me is not shipping a part that you have sold to a member that sent funds for the part plus shipping in a timely manner. After a couple of weeks regardless of your personal situation excuses just don't cut it. Anyways please mods get involved but is it time to tighten the rules again,maybe ask sellers to pay a nominal fee yearly for selling privledges to show seriousness. Lets get some input going. To quote Barney Fife " lets nip this in the bud" Thanks.
