> People want their data to be public and all of the benefits that comes with public data but then they want to chose who gets to see it
Can you really not imagine a world where a person accidentally or in poor judgment uploads something private to their own site (their real name, home address, credit card#, or any piece of highly damaging information that could cost them their careers) and wishes for it to be removed? (but can't because many of these scraping sites never respond to takedown requests)
People make mistakes and post things they shouldn't. A mistake from someone many years in the past that they've made amends for shouldn't haunt someone for the rest of their lives.
But it does when we decide that every single line of text ever uttered online must be preserved and easily accessible by anyone for all eternity.
Blocking scrapers is an arms-race escalation because these sites refuse to remove content, and it's used as a tool for character assassination by bad actors. It's a proactive defense.
