When I first published the DAC flaw a few weeks ago, I wasn't sure if others were still using it or not. I have never used it myself. Since then I have heard that Nominet are now actively monitoring the DAC and will take action against anyone they find usingthe flaw, or having used it.
Apparently it was confirmed yesterday by Nominet's Head of Legal Nick Wenban-Smith. He said that they are monitoring it and will take action against anyone they find to be using it. I wasn't on the Virtual round table at the time it was said, but it seems clear that Nominet are watching it until they have a long term fix.
This is just a heads up, they aren't treating it as a game.
