Dogpile
Massive reaction against a specific post/person, often after a quote-tweet or cross-platform link. Thousands of replies within hours, mostly from strangers who never saw the target before. Forces either ratio, delete, or platform-switch.
Twitter era 2014-2023 was the peak of dogpiling. Mechanics: viral quote-tweet → algorithm pushes to millions audience → 99% is "dunk" or harassment, 1% substantive critique. The target can't handle the notification flood, suffers sleep loss + panic attacks. "The main character of Twitter" = today's dogpile target. Platform defenses: rate limits on quote tweets, "Limit reply" to a subgroup. Bluesky added "detach quote post" — the original poster can retroactively remove their post from a quote thread.
