Researchers from the FTC had fun creating some undercover email accounts, publishing the addresses on various websites, then sitting back to watch the spam roll in.
And roll in it did, in its thousands.
But considerably less spam rolled in to those addresses at ISPs using spam filtering technology. And those addresses that were posted online in disguised form (readable to humans, but not machines) only got one piece of spam in total.
The obvious, but still worthy, conclusion: don't post your email address online carelessly and use an ISP that has filtering technology. (Unless, like me, you don't trust filters to let all the important mail through, too).
