PJ, I'm not commenting on the rest of your post as I fully understand your point.
However, all that has been asked here, and mentioned to several sellers in the past, is that if you have a commercial interest in selling items here, then please contribute a little bit to the forum. If I plan on selling things on eBay for example, I'm going to have to expect to pay eBay listing fees. If I want to market to members of my local Chamber of Commerce, I know I'm going to have to pay to be a member there.
If I'm selling on PL then, it's not unreasonable to ask that I be willing to contribute here too.
As long as it's posted in the buy and sell thread, by all means, post your products for sale but, throw a bone to this outlet here that's been provided to you, for it's upkeep. That's all.
