Why HARO died.
Volume killed it. In its final years, popular queries drew hundreds of responses, and a growing share were AI-generated boilerplate signed by invented 'experts'. Journalists stopped reading past the first screen of replies, then stopped posting queries at all. Cision's rebrand to Connectively tried to fix the signal-to-noise problem with a new interface; it did not, and the platform closed.
The lesson carries into whatever you use next: any open request channel degrades as spam scales, so the advantage keeps shifting toward sources who answer fast, credibly, and specifically.
