The Southern Poverty Law Center filed a lawsuit Tuesday on behalf of a woman in Montana against the white supremacist website the Daily Stormer, alleging the site urged its users to harass and attack her.

The plaintiff in the case, real estate agent Tany Gersh, claims that Andrew Anglin—the founder of the neo-Nazi publication—invaded privacy of her and her family, caused emotional distress, and violated Montana’s anti-intimidation rules.

Gersh’s case is the culmination of events that started in December when Sherry Spencer, the mother of alt-right leader and outspoken white supremacist Richard Spencer, accused Gersh of extorting her and her business.

Anglin caught wind of Spencer’s accusations against Gersh, who is Jewish, and called for a “troll storm” directed at her and other Jewish citizens in the town of Whitefish, Montana. The Daily Stormer encouraged its members to “stop by” Gersh’s house and published her address and phone number.

The original post encouraging the trolling was followed up with several additional posts, including one suggesting Daily Stormer readers specifically target Gersh’s 12-year-old son.

The posts resulted in more than 700 instances of harassment according to the lawsuit, including those received via phone, mail, email and social media. Many of the attacks included anti-Semitic slurs and graphically violent images, including a Photoshopped image of Gersh being sprayed with gas.

Many of the messages also included thinly veiled threats against Gersh and her family, like promises that she would be “driven to the brink of suicide,” or “get thrown in the oven.” One phone message was just the sound of gunfire.

The Southern Poverty Law Center plans to argue Anglin and the Daily Stormer’s behavior is simply the act of violent hate groups “adapted for the digital age.”

While it may be clear the Daily Stormer played a role in Gersh being the recipient of vitriolic messages, it has historically been difficult to achieve legal punishment against online harassers, even in cases where threats are real and actionable.
