Yes. However, it still doesn't prevent the keyservers from being
loaded with a lot of useless signatures. I don't know how this would
affect the load of the keyservers.

To solve this the keyserver software has to be modified, for example to
delete expired sigs, or at least not to send them out. But it will keep
the gpg keyrings clean.

Or at least have them remove all GD sigs except the last issued.

Increase the expiry date of their signature to someting more usefull,
like a year.

That would blog my keyring if there are some keys on it that are placed on
the GD.

However, what about an GnuPG option like --clean-keyring that deletes all
expired sigs, or perhaps deletes all (expired or not?) sigs from a given
key, from your pubring? If the blogging occurs, you could at least clean
up your keyring without manually deleting all those signatures.
