You may as well announce both the same /24 and /25s if you can...though 
those probably won't make it far.  If they hijack something less 
specific than a /24, go one bit more specific than the rogue 
announcement.

After that, try contacting the rogue ASN's upstreams.  After that?  See if 
you can find a backhoe for hire?
