Totally get where you are coming from K. If someone is helped in some way by a member here, the courteous thing would be to pay it forward and help the next member. However, if you are the sort of person who lives by that philosophy, and you help a member out, and in the end you see them making a profitable benefit from your free or cheap help, I can imagine that doesn't feel very good.
A good example of this: Ubi's 7032 being listed on eBay for $40k
