The only thing people will do about .XXX is buy them ALL the day they go on sale.
Later down the road when we get forced into giving up our .coms and all stuck in this online red light zone, we will all claim "we never saw it coming" and you will see 10000 rants on the boards about it. And even then, nothing will be done about it.
The adult industry lives with it's pants around it's ankles waiting to be fucked over and over and over again. We never learn our lesson, we don't police ourselves and we will do anything for a buck. Few webmasters are even responsible when it comes to paying another webmaster, let alone when it comes to something as serious as this.
This is not about the kids, this is about money. On all ends.
This is simply a power business move. This is not going to stop the creation of child porn or access to it.
After 2257 and after we all have .XXX... what do you think is going to happen? It will not end there.
