Bad idea if (when) taken too far...
> all people have to do to keep porn off their machines is block all .xxx domains. If, as an existing "provider", you don't nab the .xxx when given the shot you lose the ability to resolve the site.
And, once again, I ask what happens to adult businesses like mine which deals in leather bondage gear and, thus, has adult content, but does not deal in "porn"?
Not forgetting, of course, the massive rush there will be to register sex.xxx or xxx.xxx etc, plus the cyber-squatters getting in on the act who will no doubt try to register affordable-leather.xxx and sell it to me for a hefty commission because I own the .co.uk version of it.
