Blackholing the RIAA and hating them is pointless, that is what they are there for. Blackholing them accomplishes nothing. If you want to cause change you need to go after the labels. The labels are the member organizations which fund the RIAA. It's the labels who need to be stopped, the RIAA is just their puppet and shield.
However, blackholing is effective in regards to anti-piracy bots that rove the Internet like web spiders attempting to discover copyright violations by verifying P2P data that has been collected elsewhere. Since March of 2001, we have used complaints originating from anti-piracy organizations hired by various labels, most notable Sony, to maintain our own BGP blacklists. Since we have a significant xDSL customer base, we frequently received copyright infringement complaints from these organizations. This policy has eliminated those complaints. We were able to reduce legal exposure and reclaim some of the protection once afforded by open carriage by preventing these intrusive verification tests from even occurring. However, we do act on all complaints that we receive. Ben
