I really like the idea of the service as I've used various addresses in a domain to test if my data was actually protected by those that claimed that they wouldn't sell it or release it without my permission. For the majority of those sites, the addresses I used quickly made it into spammers address books.
But back to the question... Call it a prediction if you want, but I can forsee at least a token effort to get a law passed to make this sort of thing illegal. Or you can just call me skeptical.
