With all due respect, but why should a GnuPG user not been allowed to decide
by him/herself which signatures he/she likes to have on his/her pub key? 
I don't get it, seriously. BTW. maybe a language barrier, but an unwanted 
signature for me is a signature which contains crap or false content which 
does not help the Web of Trust in any way and which i or others don't like
to see on our public keys.

P.S. last post for today, getting late here.
