YouTube initiated a ban on commentator Russell Brand on last week that prohibits the celebrity from making money on its platform following accusations of sexual assault against the British comedian.

"If a creator's off-platform behavior harms our users, employees or ecosystem, we take action to protect the community," YouTube said in a statement.

Mr. Brand, a former self-confessed sex addict, was accused of sexual and emotional abuse that allegedly took place several years ago by four women in an investigation by the Times of London, The Sunday Times, and Channel 4 "Dispatches."

The 48-year-old actor denied the charges in a video he shared with his 6.6 million YouTube followers over the weekend.

"These allegations pertain to the time when I was working in the mainstream, when I was in the newspapers all the time, when I was in the movies. And as I've written about extensively in my books, I was very, very promiscuous," Mr. Brand said. "Now, during that time of promiscuity, the relationships I had were absolutely always consensual."

A day after the allegations were reported, police in the UK said they had received a report of a sexual assault allegedly involving Mr. Brand in September 2003.
