TV Watchdog Ofcom is assessing hundreds of complaints made over Winston McKenzie on Celebrity Big Brother 2016.
Less than a day into the series and the former UKIP member caused controversy with comments he made in his opening VT.
The 62-year-old, who hopes to become Mayor of London, said: "I'd cope with a homosexual in the house.
"I guess I'll just have to stand with my back against a brick wall all the time."
Ofcom says it will assess the complaints it has received before deciding whether or not to launch an investigation.
Channel 5 have declined to comment but Big Brother hosts Rylan Clark-Neal and Emma Willis have spoken out.
"His VT didn't do him any favours," Emma said yesterday before explaining how she didn't have time to challenge Winston on his remarks in the live launch due to time constraints.
She added: "I think we have to see what he's like in the house and what happens in the house with him.
"I don't think he'll last very long. That's when the challenges and the questions will come."
Meanwhile, Bit On The Side host Rylan said he "couldn't wait" to speak to Winston.
Rylan told ITV's This Morning: "I've had a little wall made, so when he comes out, I'll say, 'Winston, I am a homosexual. I don't know if you know that. There is a wall, if you feel you need to stand up against it'."
He continued: "With the profile VTs, I get that you want to be a little controversial, but to say something like that, if you look at homophobia, it's on the same level as racism.
"If someone said something like that about a black person or a white person, there would have been an uproar."
Celebrity Big Brother 2016 continues nightly on Channel 5.
