You cannot provide any security over the Internet, much less any other form of communication. We actually post periodically warnings not to trust our site. Don't believe us. We offer no protection. You're strictly on your own.
We also say don't trust anyone who offers you protection, whether it's the U.S. government or anybody else. That's a story they put out. It's repeated to people who are a little nervous. They think they can always find someone to protect them. No, you can't. You've got to protect yourself. You know where I learned that? From the cypherpunks.
