The industry taxonomy for fraud too complex for simple filters to catch. General invalid traffic ([GIVT](https://www.adlingo.org/glossary/invalid-traffic/)) gets caught by lists: known data centers, declared bots, crawlers. SIVT is the deliberate stuff. Hijacked devices, [botnets](https://www.adlingo.org/glossary/botnet/), residential proxies, spoofed apps, falsified viewability. Catching it takes behavioral analysis across multiple signals.
