I want to know who serve for dedicated server which accept gambling and pornography ?

Are the items legal?

Unless online gambling is illegal in your state or your showing illegal porn, I dont think anyone will care.

would it be illegal for the state the client is paying from or where the server is located, or both?

where the business entity is based...

thats why places like casino-on-net can exist on US servers n stuff... heh

that can't be right... lol... wouldn't hosting illegal stuff on US servers = abiding illegality? a crime in itself.
