Why are there always super obnoxious scrapers out there? It doesn't even make sense from the scrapers perspective because it raises the chance of being blocked and having annoying anti bot measures introduced. It especially makes no sense in this case because archive.org would be happy to give them the data for probably less than whatever they were going to spend on AWS. There's no manners anymore.
