Married At First Sight Australia's season five stars have lashed out at Channel Nine after discovering they were blocked from the show's official Instagram account.
With another season kicking off in the coming weeks, the show's social media team appears to have made the move to prevent past contestants from commenting on the new singles.
Many of the former reality TV stars took to their own social media platforms to share their outrage, threatening to expose the show for the way they've been treated.
"Wow! I've been BLOCKED by @mafs," Sarah Roza wrote in an Instagram post.
"Maybe they're worried I'll spill the beans on what REALLY happened behind the scenes and expose their negligence, lack of duty of care and mistreatment of pretty much ALL of us on the show."
Controversial contestant Dean Wells, who became the show's villain after an affair with co-star Davina Rankin, promised he'd make a tell-all YouTube video in response to the social media snub.
"Guess they don't want the truth getting out and ruining their fairytale," he posted online.
