5M to protect against scraping? That sounds... a bit much, no? 34 employees with that one task for 2 years doesn't sound believable to me. Why is WorldCat worth anything anyway?
Defendants, through the Anna’s Archive domains, have made, and continue to make, all 2.2 TB of WorldCat® data available for public download through its torrents,” OCLC wrote in the complaint it filed in an Ohio federal court.
Seriously... I've downloaded 2TB in a week before.
I get that it's not about the bandwidth, though; it's about needing to upgrade their security since they scraped the site without needing to log in, so obviously their site wasn't secure. They're claiming IT costs as damages.
