buyer beware of late

Did anyone else respond to the "unbeleavable" listings lately, like the B&W 800's for $3000 or the N802's for $3200...new members with no feedback. I received the message from Audiogon saying the members were "questionable" and not to do business with them. Same thing happened today with a listing for a Jadis integrated amp. I guess the only safe bet is to stay away if there's no feedback..but that doesn't do much for the legitiment new members trying to get established.
