The entitlement of so many modern vibe coders (or as we called them before, script kiddies) is absolutely off the charts. Just because there is not a rule or law expressly against what you're doing doesn't mean it's perfectly fine to do. Websites are hosted by and funded by people, and if your shitty scraper racks up a ton of traffic on one of my sites, I may end up on the hook for that. I am perfectly within both my rights and ethical boundaries to block your IP(s).
And just to not leave it merely implied, I don't give a rats ass if that slows down your "innovation." Go away.
