I think spammers got my email address from the PGP keyserver. What can I do?
Yes, there have been reports of spammers harvesting addresses from PGP keyservers. Unfortunately, there is not much that either we or you can do about this. Our best suggestion is you take advantage of any spam filtering technology offered by your ISP. • I get a “Malformed Key” error when trying to upload a revocation certificate. Why doesn’t this work? Try applying the revocation certificate to your local key-ring and then re-uploading your key to the keyserver. • I can’t look up keys on the keyserver, and may be seeing the error “connection timed out.” However, I can read this FAQ. The usual cause for this is that your machine is behind a firewall that is blocking traffic (on port 11371) to the keyserver. Please try using the email interface.
