Government efforts to block offensive Web sites are technically problematic and legally worrisome, a new study says.

It concludes that instead of precisely targeting only objectionable sites, attempts to restrict Internet addresses with pornographic, political or gambling-related content inevitably make legitimate sites unreachable too.
