Twitter CEO Jack Dorsey announced late Friday that the social media platform will unveil a stronger set of rules against sexual harassment and threats of violence after women, led by actress Rose McGowan and others, boycotted the platform.

In a series of tweets, the Twitter CEO pledged to do more to ensure that women's voices are not silenced on the platform.

"We see voices being silenced on Twitter every day. We’ve been working to counteract this for the past 2 years," Dorsey wrote. "We decided to take a more aggressive stance in our rules and how we enforce them."

Dorsey added that the new policies would be subject to stricter enforcement in the coming weeks.

"New rules around: unwanted sexual advances, non-consensual nudity, hate symbols, violent groups, and tweets that glorifies violence," Dorsey said. "These changes will start rolling out in the next few weeks. More to share next week."

Dorsey also retweeted part of Twitter's statement concerning the company's decision to ban McGowan's account on Wednesday, which sparked the boycott.

McGowan was banned after her account tweeted a private phone number, a violation of Twitter's terms of service.

"Twitter is proud to empower and support the voices on our platform, especially those that speak truth to power. We stand with the brave women and men who use Twitter to share their stories, and will work hard every day to improve our processes to protect those voices," the statement read.

Actresses and others in the media responded, with model Chrissy Teigen voicing her support for the boycott on Thursday night.

"Ladies. Let's do this. #WomenBoycottTwitter. Not because of hate but because I love this platform and know it can be better," Teigen wrote.
