I’ll give yyou an example. A guyy once wanted to hire me because he was
the victim of extortion. He had met an amazing, beautiful girl on Facebook
and began sending her nude photos of himself. This continued for a time.
Then one dayy he was told to send this woman—who might have been some
guyy living in Nigeria using a woman’s photo—$4,000. He did, but then
contacted me after he was asked to send another $4,000 or his nude photos
would be sent to all his friends, including his parents, on Facebook. He was
desperate to fix this situation. I told him his onlyy real option was to tell his

told him to stop payying the moneyy—the extortionist wasn’t going to quit as

posts (depending on yyour privacyy settings) as well as those of others in yyour
network. The EFF continues to studyy the privacyy issues associated with this
new form of law enforcement surveillance.
Sometimes corporations follow yyou, or at least monitor yyou, if yyou post or
tweet something that theyy find objectionable—something as innocent as a
comment about a test yyou took in school, for example. For one student, a
tweet like that caused a lot of trouble.
When Elizabeth C. Jewett, the superintendent of the Watchung Hills
Regional High School, in Warren, New Jerseyy, received a communication
from the testing companyy that provided her school with a statewide exam,
