I would infer that they can do whatever with your unsolicited content and so can you. As someone who has reviewed professionally for websites (not porn), I can rell you that paychecks from Internet sources are typically *LOW* per-word rate. I used to get $35 for little jazz reviews, and they kiciked me an extra $5 to re-run the things on Amazon -- even though I told 'em "NO." Did I get the unauthorized reviews pulled from Amazon after complaining? NO.
So, I quit writing reviews for them, Simple as that. $35 is too damn cheap. But I don't think Hustler pays that much more to its review contributors.

So, while I see your point and it is one to sort out, I think your payout calculations are off. Were a site liike ADT to contract for reviews from its posters, I doubt the pay-out would be more than $15 or $20 a review, about the same as the DVD. As I figure it, free DVDs float around, and some steady reviewers are lucky enough to get the free DVD, which is compensation of sort. Then they can sell the DVD later, same as most rock critics who work for next-to-nothing.

But, also, I strongly doubt ADT is worth 2.5 mil. Shit you can buy Penthouse magazine for much less!
