What ASN blocking catches
Scrapers & crawlers

Most content scrapers run on AWS, GCP, or DigitalOcean. One rule blocks the entire provider.

AI training bots

LLM training crawlers originate from data center IPs. Country rules don't catch them — ASN does.

Automated attacks

Credential stuffing, form spam, and rate abuse almost always originates from cloud VMs.

What it won't block

Real users on residential ISPs. Home users, mobile carriers, and business broadband are unaffected.
