Methbot (2016) faked roughly $5M/day of pre-roll inventory via 800+ data-center servers running headless Chrome — the largest video ad-fraud bust on record at the time.

3ve (2018) — the successor to Methbot — used 1.7M infected PCs and 700,000 IPs and stole ~$30M before the FBI, Google and White Ops jointly took it down.

News publishers typically see pre-roll completion rates of 70–85% — far higher than display viewability, which is why CPMs stay in the $20–40 range even in down markets.
