Greg Squire, an undercover agent with the NSA, provided significant assistance in rescuing a 12-year-old girl from sexual abuse, an experience he recounts in the documentary "The Darkest Web" on BBC's YouTube channel. Squire emphasizes the profound emotional toll that the job has taken on him, notably impacting his personal life and leading him to avoid social media entirely.

The documentary, directed by journalist Sam Piranty, presents a detailed account of Squire's work with a team of 50 agents from various countries, showcasing their efforts over seven years to track and dismantle networks engaged in heinous crimes on the Dark Web. The film has quickly garnered over 600,000 views within just two days of its release, underscoring the public's interest in the dark realities of cybercrime and the international collaborative efforts to combat it.

Squire's story serves not only as a testament to the bravery and dedication of undercover agents but also shines a light on the ongoing battle against online exploitation and abuse. His decision to step away from social media reflects the psychological impact of his experiences, raising questions about the mental health of those involved in combating such disturbing criminal activities on the internet.
