I am amazed at how few sites in the bitcoin community are not supporting the blackout today. I just visited most of the other pools and several bitcoin blog sites, and it seems only
BitcoinPool is supporting the SOPA blackout. We would like to encourage other pools or bitcoin related sites to join us in doing so.
We think it boils down to this: If they get the equipment in place and legislation passed then what will stop them from censoring port 8333 instead of port 53? A few thousand angry bitcoin users?
BitcoinPool is not doing a complete blackout, but every page on the site will have a blackout overlay until you click on it.
