The FBI is trying to unmask a prolific Instagram extortionist who posed as a Californian woman and tricked at least 30 teenage boys and young men into sending nude images, only to be told the photos would be shared with their families and friends unless they paid a given sum. In one case, an 18-year-old from Ventura County, California, gave over $1,500 in Apple gift cards to the blackmailer and subsequently took his own life, according to a previously unreported court filing obtained by Forbes.

The scammer has been carrying out the sextortion campaign since May of last year and their identity is not yet known. They’ve been particularly aggressive in pursuing payment from victims, in one case threatening violence against a 19-year-old and his family. The scammer also hacked into at least two victims’ Instagram accounts, telling them to hand over passwords to stop their photos from being shared, according to the FBI. The victims told police they tried to get their accounts back but were unsuccessful. Both were unavailable when checked by Forbes.
