Anonabox is not a magic bullet!

Yesterday, a lot of mainstream media (e.g., WIRED) started reporting about anonabox, an "an open source embedded networking device designed specifically to run Tor.", to quote their Kickstarter campaign.

For those of you who don't know what Tor is: It's a network run by volunteers that anonymizes your internet traffic. With everyone in the network using someone else's address from time to time, it is becoming harder for an observer (e.g. the websites you browse) to find out who is who.

Advertisements & Social Media kill Anonymity
