In the Criminal Minds episode , the "Samaritan Cult House" refers to the base of operations for a twisted vigilante group led by a man named Benjamin David Merva .
The group utilized an abandoned property—often referred to as the cult house—where they held captives and indoctrinated members.
The cult used "Rule 34" of the internet (the idea that if something exists, there is porn of it) as a macabre inspiration for their crimes, documenting their "good deeds" and sharing them within their dark web community.
