Exposing the People Behind Deepfake Porn Sites with Bellingcat Investigator Kolina Koltai

This week, Sam is in conversation with Kolina Koltai. Kolina is an investigator, senior researcher and trainer at Bellingcat. Her investigations focus on the people and systems behind AI companies and platforms that peddle non-consensual deepfake explicit imagery. They discuss how she found herself in this field, her recent investigation (bellingcat.com/news/2025/12/15/mark-resan-refa…) uncovering the man behind two deepfake porn sites, and how it feels to watch these sites go down after exposing the people running them.
