IP not found ... discarding as fake

IP not found ... akbvci.salaryquilt.net discarding as fake:   I'm seeing this fairly often - it resolves fine here.   I'm assuming that the spammers just block Spamcop's
nameservers.
   
  Is there an easy way to get the abuse reporting address from the IP after I look it up?

  Could Spamcop use some sort of distributed network of resolvers to make this harder to block?   Sort of a reverse Blue Frog - volunteers could download a remote
resolver utility that Spamcop could call on as a secondary resource in resolving otherwise blocked names - then cache them.
