How can four Linode servers produce enough load to "severely tax" Twitter servers? Not to mention that customers of Linode can be pretty much anywhere in the world, so good luck even getting the case going.
The suit in itself seems bogus. Scraping is perfectly legal as long as you don't collect PII or copyrighted material.
Linode will probably hand over the names if sufficiently pressured, but even then. Non-US citizen has a near zero risk of ever paying a dime. Even US citizens will probably be fine.
It's odd they're suing for release of customer information behind 4 specific IPs. If they knew the 4 specific IPs were degrading the experience, they could easily block them.
