After a previous punishment saw the group having to live off basic rations, it seems some have yet to learn their lesson.
In last night's show, Lewis Flanagan, Cian Carrigan and Zoe Jones are hauled into the Diary Room by Big Brother.
Big Brother told the group: "The rules regarding the discussion of nominations have been explained to you on several occasions. Over the last few days all of you have broken these rules.
"You will be punished collectively. Would one of you collect the item from the hatch."
Inside the hatch, the trio found a set of shackles as Big Brother explained: "Big Brother will be shackling the three of you together until further notice."
Lewis, Cian and Zoe found themselves locked together and had to stay locked together everywhere they go throughout the house, except for the toilet.
However the punishment became too much for Lewis, who ended up ripping off the shackles.
In tonight's episode, the trio are again called to the Diary Room where all three are fined 150 Big Coins for breaking the rules regarding their punishment.
The latest rule break follows housemates heading into the Diary Room on Sunday night for this week's nominations.
Akeem Griffiths, Brooke Berry, Cian Carrigan, Sîan Hamshaw and Tomasz Wania are all currently up for Friday's latest eviction.
In a twist, housemates were asked to give 'positive nominations', naming their two favourite housemates. The housemates with the fewest nominations would face the axe.
This was Akeem, Tomasz and Cian with zero and one nomination each respectively. In addition, viewers also voted for their favourite housemate in a secret poll. The three with the least votes were Brooke and Sian, as well as the already nominated Tomasz.
As a result, Akeem, Brooke, Cian, Sian and Tomasz all currently face the latest eviction this week.
However they'll all get the chance to save themselves in the weekly game changer task, along with Zoe who is the richest housemate.
Big Brother 2018 airs Sunday to Friday at 10PM on Channel 5.
