Russian television anchor Pavel Lobkov was in the studio getting ready for his show when jarring news flashed across his phone: Some of his most intimate messages had just been published to the web.

Days earlier, the veteran journalist had come out live on air as HIV-positive, a taboo-breaking revelation that drew responses from hundreds of Russians fighting their own lonely struggles with the virus. Now he'd been hacked.

"These were very personal messages," Lobkov said in a recent interview, describing a frantic call to his lawyer in an abortive effort to stop the spread of nearly 300 pages of Facebook correspondence, including sexually explicit messages. Even two years later, he said, "it's a very traumatic story."
