Your key on the SKS servers has a lot of subkey signatures
misplaced on userids:

  %gpg -v --keyserver keyserver.noreply.org --recv 0x604DE5DB
  gpg: requesting key 604DE5DB from hkp server keyserver.noreply.org

but it looks like most of its subkeys are in order:

  %gpg -v ...

except for that nagging "gpg: key BF15490B: skipped subkey,"
which would seem to refer to:

 (NB:  output from keyserver.kjsl.com:11371)
 sub  4096g/788FA859 2002-07-25 [subkey, revoked?]
      Key fingerprint = 43A9 5BF3 7FF4 76EE 4694  DBCB E47E 70A6 788F A859

 rev  0x28  BF15490B 2002-03-30 [keybind, hash: type 2, a9 dd]

which only has bad signatures from other subkeys and isn't even
importable from http://strugglers.net/pubkey.asc :

  %gpg --import pubkey.asc 
  gpg: key BF15490B: "Andy Smith <address@hidden>" not changed
  gpg: Total number processed: 1
  gpg:              unchanged: 1

  %gpg -k 788FA859
  gpg: error reading key: public key not found
