So far the US is only cracking down on domains in the .COM TLD. Do you guys think the US will eventually crack down on non-US-owned TLDs that are operated by US entities, such as .CO (operated by NeuStar)? And after that, perhaps a doomsday scenario, will they eventually force US-hosted DNS caches to expunge records that are related to criminal activity as, in a way, they are aiding and abetting..
