Quick: How do you completely cloak your online activities from the world? There's got to be some relatively easy, surefire means by which to do it, right? Some advanced IP-masking software out there that hackers use, or some such?
It's not that easy. Not that easy at all.
WikiLeaks recommends that its informants use Tor for anonymity. That's what I used to run my site for the first couple months, operating online with a masked IP address, thinking it was a watertight guarantee of anonymity, until I learned that it doesn't really guarantee shit.
"The mask is just to keep my face warm."
Then there's the fact that the Internet doesn't take kindly to people with masked IP addresses. Try logging into Gmail while signed into Tor and you'll discover that Gmail instantly locks you out. Trying to build and operate a WordPress blog with a masked IP address is like trying to play piano wearing boxing gloves. Features are stripped to the bare minimum, and loading times are in 1990s territory.
What about public computers, you say? That's mostly how I ran the blog for the first few weeks, going from public computer to public computer, using libraries and FedEx stores, until I realized there were cameras in all those places watching me peck away at my controversial little project. Anyone truly determined to find out who was behind the site would be able to do it.
