Pinterest, stop voicejacking!: I agree that this practice is distasteful. The rise of social media means that we’ve all started to communicate in the first-person (-ish) a lot more. This process can be hijacked pretty easily by unscrupulous apps and organizations.
Voicejacking is the practice of communicating on someone else’s behalf without telling them you’re doing it. It’s commandeering someone’s voice.
Anyone remember the Shelfari debacle?
Socialcam (I refuse to link it) does this a lot on Facebook by causing people to unwittingly advertise videos they watched (sometimes with embarrassing content).
