I do not beleive it will happen based on the freedom of speach Larry Flint arguement. However porn gambling and other such sites can been banned or at the very least make it very difficult to operate these sites.

Some states in the US have banned online gambling by going after the operators of the sites regardless where in the world they are based and have had some success in prosecutions. There are obviously ways site operators can get around this but it does make operating more difficult.
