If you don't have the private key, then yes, right. There is nothing
you can do about it.

You really can't. Even if one operator did remove the key, keyservers
synchronize with each other, so the others could just put it back
later. You'd have to remove it from all keyservers... and even then
if someone accidentally resubmitted it, you'd have to go through this

Nope. It's an inherent scaling problem of the keyserver net. I've
seen estimates that the majority of the keys on the keyserver net are
not used for one reason or another, but can't be deleted. Even with
the garbage keys, the keyserver database isn't too large to be served
The PGP company is running a different sort of keyserver at
http://keyserver.pgp.com. This type of keyserver allows you to remove
keys if you can prove (by answering an email challenge) that you have
access to the email address on the key. This keyserver obviously does
not synchronize with the others, however.
