But are they Streisand-effecting it a bit at the same time or taking the piss, could be completely off, but by giving them attention could be theres at least a sliver of truth somewhere in what they're 'leaking'? lol
It wouldn’t be Big Brother without some rando claiming to work on the show themselves or knowing somebody who works on the show.
They pick up known facts and make educated guesses. Some of them hit and people start to believe all of them.
It happened with the current BBUK reboot as well. There was one guy who claimed to be a senior producer and made wrong claims but then the UK reboot had echoes in the diary room and that guy said that they are working on it. When it was indeed fixed, I think a lot of people were sold on him.
But then he got more stuff wrong, people called him out and he turned completely crazy (first having "his wife" post that he quit his job because he was in deep depression from people being mean to him, then sending people fake cease & desist letters).
When the German civilian reboot was announced, they wouldn’t confirm the channel at first. So people speculated that it might air on a different channel than the celebrity version. Some rando then claimed to be involved with the show and said it would move back to its original channel (hence why they wouldn’t reveal the channel yet). Some people took him seriously because the original channel cancelled one of their soap operas and they took it as making room for Big Brother. Of course it turned out to be fake.
Not Big Brother but "Uncle Cameraman" used to be a bit of a meme in the Survivor community.
There have been some proper leaks over the years and I think the vegas girl from BBUS was the most prominent one that worked on the show as a story producer and would leak stuff during the season (but also post a lot of bs).
But at this stage of BBAU, I would assume that only senior production crew would have an idea on what they want to do during the season. And it’s very unlikely that they would leak major twists.
