Has it? Can you give me an example of a site that is hard to scrape by a motivated attacker?

I'm curious, because I've seen stuff like the above but of course it only fools a few off the shelf tools, it does nothing if the attacker is willing to write a few lines of node.js

i guess the lazy way to prevent this in a foolproof way is to add an ocr somewhere in the pipeline, and use actual images generated from websites. although maybe then you'll get #010101 text on a #000000 background
