If anyone has any heuristics for ensuring that lists don't have automated new-domain or SWIP gleanings, I'd appreciate them; for now we'll just search for hostmaster@, ipspace@, and other role-looking accounts.
a heuristic that i would use would be: please don't purchase "contact" lists from people. please don't hire marketing folks who think that this is a good idea. sales the old-fashioned way still works, you know. learn about people in your market, get to know what they want, contact them individually when you think you can make a sale. since when did blind email campaigns to lists of people whose _origin you can't even determine_ become a reasonable-sounding sales technique? this isn't postcard-in-the-mailbox stuff, guys. and the people buying it aren't likely to impulse-buy, anyhow. jeez. s.
