Channel 4 has taken the decision to pull every previous series of Married at First Sight UK from its streaming services.
The broadcaster confirmed the move follows "very serious allegations of wrongdoing" involving a limited number of former participants.
The removal comes ahead of a BBC Panorama documentary set to air this evening, which examines claims made by women who appeared on the popular reality programme.
The investigation, titled The Dark Side of Married at First Sight, is scheduled for broadcast at 8pm on BBC One.

According to the BBC, two of these former contestants claim they were sexually assaulted during their participation in the reality series.
The documentary features testimony from all three women, though their identities have not been made public.
Similarly, the names of the men facing these accusations remain undisclosed.
All three men at the centre of the investigation have denied any wrongdoing, the BBC confirmed.
The Panorama programme examines whether the show's welfare procedures failed to provide adequate protection for contributors, potentially leaving them vulnerable to harm during filming.
Both Channel 4 and CPL Productions, the independent company responsible for making the series, have defended their approach to participant safety.
The broadcaster and production firm described their welfare protocols as "robust and comprehensive."
