In fairness to AVN, I think having people at the booths scan admission badges and acquire information is not selling a list, it's a shorthand form of collecting contact info willingly provided by the attendees at the show.

I think I remember, when looking over AVN's package of services, that companies that exhibit could purchase (or maybe automatically receive) a copy of the attendee list for that year, but to me that is a little different than selling the attendee list to anyone who asks, and I have less problem with it.

In other words, if I attend a show - ANY show - I sort of expect that the companies exhibiting will be able to pester me. I am pretty sure that CCBill does this with Phoenix Forum as well. But I would not be so happy to find out that the show producer is selling my info to anyone and everyone.

In this case, the company sending the junkmail did attend Internext as an exhibitor (at least, according to their letter) so I don't really think AVN has done anything any different than what any other show producer would do.
