I don't like low ballers either but this business strategy makes sense. Why offer someone $XXX when they are willing to take $50? You don't know who is on the other end of the whois, so you don't go around saying "Well...I want to offer you $1,000 but will you take $50?" Better strategy for you, if you see them listing the .net at $4,000 is to counteroffer using that information to your advantage.
