New Global Directory of OpenPGP Keys
Gemini writes "The PGP company just announced a new type of keyserver for all your OpenPGP keys. This server verifies (via mailback verification, like mailing lists) that the email address on the key actually reaches someone. Dead keys age off the server, and you can even remove keys if you forget the passphrase. In a classy move, they've included support for those parts of the OpenPGP standard that PGP doesn't use, but GnuPG does."
From the FAQ:
Will I get spam if I use the PGP Global Directory?
No. Searches of the PGP Global Directory are limited to one (1) response, thus making gathering email addresses from the PGP Global Directory one of the least-effective ways of harvesting email addresses for spammers.
