网暴 is shortened from
网络暴力 (online violence). Became a major public-policy keyword in China after several high-profile suicides linked to coordinated harassment campaigns (e.g. the
粉发女孩 case in 2023, where a young woman took her life after being attacked online for dyeing her hair pink). The Cyberspace Administration runs periodic
反网暴 (anti-cyberbullying) campaigns.
