The scariest part of an online argument is getting doxxed by the other side.
Tips
register
Internet slang since ~2022. The 'doxxing' sense is informal; news media use 人肉搜索 (rénròu sōusuǒ, 'human flesh search') for the same act. The literal sense ('open a box', e.g. unboxing a package) still works - context disambiguates.
culture
Origin: 'opening a box' = revealing what's inside = exposing private info. The doxxing wave on Chinese social media around 2023-2024 prompted Public Security Bureau crackdowns. Distinct from 网暴 (wǎngbào, online mob abuse) - 开盒 is one tactic within a 网暴 campaign.
mistakes
Don't confuse with 拆盒 (chāihé, 'unbox', as in unboxing videos) or 盲盒 (mánghé, blind box / mystery box collectibles). 开盒 in those contexts is fine literally; the doxxing meaning is contextual.
