> PoW is minor for botters
But still enough to prevent a billion request DDoS
These sites have been search engine scrapped forever. It’s not about blocking bots entirely just about this new wave of fuck you I don’t care if your host goes down quasi malicious scrappers
"But still enough to prevent a billion request DDoS" - don't you just do the PoW once to get a cookie and then you can browse freely?
Yes, but a single bot is not a concern. It's the first "D" in DDoS that makes it hard to handle
(and these bots tend to be very, very dumb - which often happens to make them more effective at DDoSing the server, as they're taking the worst and the most expensive ways to scrape content that's openly available more efficiently elsewhere)
Reading TFA, those billions requests would cost web crawlers what about $100 in compute?
