How to disable/delete key from keyservers

[Manfred Mayer]

Hi,

i have generated a key with one additional subkey and 4 
userid's.

I have played with all the options like adduid, sign, 
trust, revoke and expire for test purposes and to become 
familiar with the functions. I also updated sometimes the 
keyserverdatabase, to see what happens.

Now the key looks very confusing.

Is there any way to delete the key from the 
keyserverdatabase, or to get rid of the garbage that the 
key now contains?

Do i have to create a new key?

What's up with the expiration date? Does the keyserver 
delete the expired keys after a distinct time to clean up 
the database. 

Yours sincerely
