Privacy-savvy marchers might have known to avoid a web form asking for their information. The far right and its opponents often wage controversial doxxing campaigns against each other, with fascists and anti-fascists posting their rivals’ personal details online in attempt to intimidate them or reveal their identities. After the first Unite the Right rally in Charlottesville, Virginia, some white supremacists cited doxxing campaigns as the reason they would not participate in a future rally.

That didn’t stop approximately three dozen people who allegedly signed up for the mailing list or tried to reserve anti-antifa shirts. This week, days before the march, the site started publishing those people’s names, and sometimes their addresses.

“The following people still have not paid for the shirts they ordered,” the site’s publishers wrote above a list of several dozen names. “We’re hardworking organizers who paid hard-earned money out of our own pockets to have these shirts printed. The fact that our fellow patriots are now shirking their obligations is alarming to us.”
