Despite the controversy the incident has attracted, Channel 4 aired the conversation in its entirety.
According to unofficial overnight figures, 4.6m viewers - a 26.4% share of audience - watched last night's instalment. By comparison, the previous night's episode of 'Big Brother' was watched by 3.7m viewers representing 19.6% of the audience.
By 1pm today, Channel 4 had received 922 complaints about the removal of Emily and by 3pm Ofcom had received 270 complaints. A Channel 4 spokesman said he did not know whether there were any indications the complaints were coordinated.
Channel 4 had also received 68 messages of approval for its decision to remove Emily.
An Ofcom spokesman said: "We will make an assessment and a decision whether to proceed in regards to our broadcasting guidelines in the next few days."
Channel 4 had been hoping the eighth series of 'Big Brother 'would steer clear of any controversy, in light of Ofcom's damning judgement on the way it handled the 'Celebrity Big Brother' racism row in January.
In a bid to make the latest series as upbeat as possible, an all-female cast of contestants was introduced into the house. However, ratings are down by as much as 15% on the last series and 2m viewers turned off during the first week of the new series.
It also emerged this week that food and drinks giant PepsiCo is not advertising around the programme in light of the 'Celebrity Big Brother' row.
Channel 4 will be hoping the audience for last night's 'Big Brother', which accounts for 25% of the channel's annual advertising revenue, does not dramatically drop off as the latest controversy dies down.
Elsewhere, a new ITV1 drama called 'You Can Choose Your Friends' got off to a modest start, with 3.3m viewers and a 15.4% share, in the 9-10pm slot. It was up against Five's US import 'House', which was watched by 2m viewers and a 9% share.
