Big Brother 'deletes' gay brother's reply

An attempt by the brother of gay Big Brother housemate Jason to explain that the family supports him was deleted from the show's official Facebook page.

Jason revealed on Wednesday's episode how coming out fractured his close relationship with his parents and his extended family have shunned him.

"I was quite close to them (my parents), but that's kind of when ... the relationship went downhill," Jason told the 15 other housemates on the Nine Network reality TV series.

"The rest of the extended family don't want to know about, and don't talk about, it."

Jason's brother, Jonathan Roses, took to the Big Brother Facebook page after Wednesday's episode to explain his family's side of the story.

Big Brother executive producer Karen Dewy says a post was originally hidden by Facebook's filter.

"One of Jonathon's comments was hidden by Facebook filters and then Nine moderators allowed it to appear," Dewey wrote in an email to AAP.

"The same comment was then manually removed by our moderators when it was posted a second time."

Roses had said his parents loved Jason and, while it had been a tough time for everyone, the family was behind him going in to the Big Brother house.

"Hi everyone, I'm Jason's brother, and I would just like to say that my parents love Jason," he wrote.

"A 2 minute description on tv will never do the story justice.

"It was certainly a tough journey, but we support him 100%, and my mum in particular has been the most actively supportive person behind his big brother push.

"There was no turning of backs, no disowning, we love him and support him for who he is. Thanks for reading. And please continue to support my brother," Roses wrote.

However, the post, which was first revealed on the Behind Big Brother website, was deleted and Roses then asked why his reply to Jason's story about coming out was removed.

"Can I ask why you deleted my comment about my brother and how my family loves and supports him?," Roses wrote on the Big Brother Facebook page.

"They deleted my comment everyone."

These comments were also deleted.

A Nine moderator of the Big Brother responded to Roses by saying his posts were not in keeping with the site's guidelines and "repeated behaviour may result in people getting banned."

Since then Roses Facebook page has mysteriously disappeared.

Roses has been contacted for comment.
