Rich, yes it does seem to be the same ones (myself included) posting on this subject. Since it's been a while, maybe even a full 6-8 weeks since we discussed it, I'll add my 2¢ worth again.
Those that would like to place the "commercial" use rules at anything more than renting to family or anything that makes a "profit" or anything over dues; are (to borrow a word from my teenage daughter) "delusioned". It is wishful thinking on their part and certainly in denial of the full view and obvious intent of the legal documentation. It may or may not be harmful to the general membership, but that is irrelevant as it is part of the rules we all bought into when we paid the big bucks for DVC. I would venture to say that only in a dramatic extreme would it have any effect on the general membership much less be truly harmful to any of us. Obviously if one takes a room to rent, that leaves one less room for another member and may leave one person on the outside looking in. This is true when I use my points renting or not. It's also true when I only use my points for Sun-Fri, if I get a GV for only 6-8 people (or a 2 BR for 3-4) or if I cancel at 31-60 days out and I'm sure many other examples of practices that are common place and might happen to be detrimental to another member.
I've rented out a few times over the past 3-4 years and certainly don't consider it for profit especially since the amount I've made over my dues is less than I could have made in working an extra weekend or two during the entire time in question. I've certianly spent more time, effort and energy than I would have if I were to work an extra few sessions. I find it enjoyable to communicate with so many interesting people while discussing DVC and Disney in General. I consider those I've rented to my friends and I'm fairly certain that at least most of them feel the same way about myself.
Also, the method a person choses to rent out their points is their personal choice. As long as it is within the rules of DVC, I don't see how it would make any difference the method used, at least from a rules compliance standpoint. And I would consider the final rental price irrelevent. Ebay, Yahoo, advertise points, make reservations first; what is the difference. I personally have thus far chosen not to schedule time then rent it out, just my personal choice. The problem I have with ebay and the like is not the price or the fact they advertise that they have everything, it's the fact that some of the adds are totally misleading. Not the lack of housekeeping c**p, just that the tone of some of them are overtly misleading and some have direct untruths.
Besides as previously established on this board so eloquently recently, it would be illegal for DVC to prevent renting one's ownership even if the POS stated specifically it was against the rules.
