You may not be aware that such questions are now commonplace by commercial spies like HBGary and ilk. So here is what you tell them buzzards openly with your nym prominent: The design of the Internet prevents concealed communication from being possible. How to prevent using the Internet to do what you want was its first design requirement. Still there have been numerous attempts to get around the Internet's fundamental prohibition against being traced. A canard has been promulagated that the Internet routes around censorship and based on that there continues to be a hope that untraceability is in the offing. TOR and VPN claimed to be able to do that but cannot, don't waste your time, they were compromised by design. Many more out there and more hidden to assure suckering. All mass communication must be capable of tracing its users, for "administration and management." Designers and sysadmins of any of these systems know that but keep it quiet to protect their jobs and investor profits. Privacy shams encourage trust in these systems as in confessionals and torture holes. There may be a way to communicate with a few people without using any means of mass communication but not with many and pretty soon one or more of them will rat on the other users, either for pay or for jealous revenge at being stooged. TOR is a fish trap. This is not limited to technological means of communication, it applies to any form, verbal, written, sign, smoke, ear wiggle, eye blink, twitch, finger, forked tongue, boogie, hickory stick, mail drop, dead drop, fake rock, gut condom, vaginal and anal beads, DNA and quanta. You might think keeping your mouth shut would do it, but no no no. Too late for that unless it was never opened begging for tit. Tits have you by the balls. So go to work and pay your dues. But even then expect to be reported to the authorities as a menace to society for asking these questions. Or, if you're broke, report your gang and its fledging means of hiding.
