On the Monday, June 25 edition of the show, Conor was shown ranting about Deana and at one point claimed that he would punch her if she threw water over him.
According to Broadcast, the show had 356 complaints after the show finished and the number has continued growing to nearly 1,000.
Conor ranted about Deana after she was the only housemate to fail an eating challenge.
While holding Deana's epilator, Conor said: "Get your epilator and stick it up your arse. We don't give a f**k! Stick it up her f**king m**ge, stupid b**tard.
"I'm gonna play loads of pranks on her. F**king piece of s**t, I don't give a f**k if I'm pulled up to the Diary Room."
Conor was warned by Big Brother about his comments and has since apologised in the Diary Room.
Lydia Louisa has also complained in the Diary Room that she feels bullied by some of the men on this year's show. Deana and Lydia face the public vote and possible eviction this weekend.
A huge number of threads discussing the issue have appeared on the Digital Spy forums with the majority believing that Conor should be thrown off the show.
In a statement, a Channel 5 rep insisted that housemates were "closely monitored at all time" and said that "Conor's behaviour was not condoned by Big Brother or any of the housemates".
They added: "Having spoken to Conor, and bearing in mind our duty of care to the other housemates, we are satisfied that he should continue to participate in the programme."
Big Brother airs every night on Channel 5.
