A dirty secret is that piracy is being abused by criminal organizations[1]. When people unknowingly access such sites to see contents for free, it generate ad revenue for those organizations, which can fund other crimes.

Are you talking about:

Broadly speaking any organisation facilitating piracy is implicitly a criminal one. Piracy is a pretty large field though and the economics of say a streaming site are going to be very different from running a torrent tracker. The fact you can use a torrent tracker without even visiting the site (Radarr/Sonarr etc) tells me that running a tracker site, probably isn't very lucrative.
