If Verizon or whatever Incompetant Inc. ISP he uses is unlikely to do anything, why not just fix it from a technical end?
Allow blocking on a more granular level, if we know his ISP, and lock out moves and redirects for the whole damn ISPs, and specifically point the finger back in the block message: Blocked because of JarlaxleArtemis/Grawp with a nice shiny link to his long-term abuse page.
If the technical means to do this doesn't exist yet, why doesn't someone create it?
