No, that list has to be constantly updated, as things come and go. xxx would be a whole namespace that could be blocked and you'd never have to worry about maintaining that portion of the filter. Assuming decent uptake of xxx, it'd relieve some things. Right now, everything is in .com, and new domains have to constantly be added to blacklists. If more new things start going into xxx than com, we'd have half as much work, since xxx is blocked right away. This is all dependent on good adoption of xxx of course, but if the TLD doesn't exist it's not even possible. So we're happy the opportunity is presented, and I think that mainstream pornographers that want social tolerance will prefer the xxx TLD as a means to illustrate their good intentions.
