Because we're not part of the FairPlay coalition, I don't think that we've really considered the various mechanisms for doing so. We've been speaking with our technical people, and there are various ways that have different pitfalls. Certainly over-blocking is a big concern. Blocking in the right way that actually is of value.... If we're only blocking something that can be easily overturned, then it's of no value.
It's a complicated question.
