“Internet trolls have a manifesto of sorts, which states they are doing it for the “lulz,” or laughs. What trolls do for the lulz ranges from clever pranks to harassment to violent threats. There’s also doxxing–publishing personal data, such as Social Security numbers and bank accounts–and swatting, calling in an emergency to a victim’s house so the SWAT team busts in. When victims do not experience lulz, trolls tell them they have no sense of humor. Trolls are turning social media and comment boards into a giant locker room in a teen movie, with towel-snapping racial epithets and misogyny.”
