We (humanity) need to invent a simple GPLv3 style license “You can derive any data on the data you see here, any derived data you sell or share should mention this place as a source and is subject to the same copyright as the source”. This will imply scraped datasets should become public and the law enforcement bodies will be able to work in an established framework to fight copyright and license crimes. Just blocking me from using any tools I want to make sense of the world around me (data on the internet sites being part of it) with crawlers and whatnot, is inherently evil, and is not logically consistent.
