The problem with nuclear in Italy is just one: how many time have you read about a public bridge fallen because of bad construction? Same for roads, houses and so on. Most of the time the reason is the company building those, trying to spend less in materials and avoiding regulations - something unfortunately not so unusual in Italy.
So imagine what could happen with a nuclear plant...
(nuclear is safe, building in Italy is often not)
just add a forged link in the main page, pointing to a page that doesn't exist. when hit, block that ip. they will crawl only the first page in this way maybe?
expanding the concept: one thing (in my opinion) is that someone scrapes content to do something (i.e. training on some data), another thing is a tool that gets some content and make some elaboration on demand (like a browser does, in the end).
I think we need to define the difference between a software (my browser) returning some web content and another software (an agent) doing the same thing.
