Anti-vax group in Europe thrives online, thwarts tech effort

Troubled by the number of unvaccinated COVID-19 patients showing up at his hospital, the French doctor logged on to Facebook and uploaded a video urging people to get vaccinated. He was soon swarmed by dozens, then hundreds, then more than 1,000 hateful messages from an anti-vaccine extremist group known as V_V. The group, active in France and Italy, has harassed doctors and public health officials, vandalized government offices and tried to disrupt vaccine clinics. Alarmed by the abuse of its platform, Facebook kicked off several accounts tied to the group last December.
