Cybersecurity has plagued this presidential election like no other in U.S. history. Earlier this week, the Obama administration indicated its plans to retaliate against Russia, in some way, for cyberattacks. Hacking came up, again, in the final presidential debate.

There is a man who is a thorn in the side of Facebook — a problem that just won't go away. In 2008, Facebook sued him, saying he was a hacker and a spammer who was putting users at risk.
