Do you want a list of active gmail address to add to your mailing list? Well, Google is giving it out completely free of charge. Just use this search command at Google to get, currently, 13,000 results; site:~.googlepages.com. Of course, it is illegal to email these people without permission but that doesn't stop most spammers.
DaveN posted a thread about this at DigitalPoint forums named Google Schoolboy Error ?? In that thread DaveN explained how he came to figure this out. He noticed a ton of new spam in his gmail account, and then did some digging to come up with the googlepages privacy concern. So spam me, why don't ya?
