[Cal.]

Emma - Kept isolated for days on end in the bedsit told she was going back in and then removed because the producers had let everyone else make up after Fight Night bar her.
Kinga - Evicted after 3 days having never entered the main house, then entered the main house in the final weeks when all the remaining housemates were just focused on winning/leaving.
Shahbaz - Bullied by the housemates for being different.
Sam B- Fell victim to bitching and got evicted after just over a week.
Jonathon - Never entered the main house and got evicted after a few days without a public vote.
Shanessa - Evicted after a week even though she won her housemate status - the producers just wanted to save Ziggy.
David - Evicted after a week despite new housemates usually given a week's immunity (can't remember whether he won housemate status or not)
Benazir - Evicted after a few days despite never becoming a housemate. No crowd and no eviction fanfare.
Victoria - Evicted after a few days through the diary room because someone thought she had evil eyes, was interviewed in the BOTS studio and then discovered a new housemate was taking her place in the house.
Biannca - Evicted after a few days in the house, had no idea she faced the public vote and only was asked a few questions outside the house by Emma.
Amy & Sally, Harriet, Kieran, Sarah - All had no idea they faced the public vote due to not being nominated by the housemates, were all evicted and replaced after just over 2 weeks in the house because the producers thought their fellow housemates were boring.
