The /web of trust/ is a nice idea, but how trustable is it? If you take a look at how many OpenPGP key servers are out there then there are a two or three main ones and not much else. Can you trust those servers? Who is maintaining them and how often? Is any censorship going on? How hard would it be for adversaries to get implants onto them? In terms of technology this infrastructure is quite old and it could have been neglected for a long time. Once vigilant maintainers might have turned lazy and gotten lax with server security, or been recruited over to the dark side.

For these kinds of reasons you might prefer to run your own web of trust infrastructure. In simple terms it's a database of GPG public keys which provides a way for users to /find out how to communicate with others securely via email/. You can meet in person and exchange public keys via sneakernet on USB drives, but most users of GPG don't do that. Instead they just download the public key for a given email address from one of the key servers.

OpenPGP key servers are not very well defended from flooding attacks. This means that an adversary could just upload a billion keys to destabilize the server and fill it with nonsense to make it unusable. Since key servers are <i>fully open to the public</i> there isn't anything to prevent that from happening.
