Twitter temporarily suspended the account of actress Rose McGowan, she said late Wednesday, after she accused actor Ben Affleck of lying as he denounced producer Harvey Weinstein's misconduct toward women.

"TWITTER HAS SUSPENDED ME. THERE ARE POWERFUL FORCES AT WORK. BE MY VOICE #ROSEARMY #whywomendontreport," McGowan said in an Instagram post Wednesday night.

TWITTER HAS SUSPENDED ME. THERE ARE POWERFUL FORCES AT WORK. BE MY VOICE. #ROSEARMY #whywomendontreportA post shared by Rose McGowan (@rosemcgowan) on Oct 11, 2017 at 9:19pm PDT

Included in the post was a screenshot of a message from Twitter notifying her the account had been suspended for 12 hours. Twitter said the account "violated the Twitter Rules," and said McGowan's Twitter account would be restored to full functionality after the 12 hours is up and once she deletes the tweets in violation of the company's rules.

McGowan's Twitter was still visible, but the social media platform said she is limited only to sending direct messages. Under a temporary suspension, McGowan can't tweet, retweet or like other content.

Since the New York Times reported three decades of sexual harassment and assault allegations made against Harvey Weinstein, McGowan has emerged as one of the most vocal actresses in Hollywood advocating for victims and denouncing Weinstein and those who worked closely with him.

The New York Times reported Weinstein reached a $100,000 settlement with McGowan in 1997 after there was an incident in a hotel room at the Sundance Film Festival.

It's unclear which of McGowan's tweets violated Twitter's rules, but according to the Washington Post, the tweet that triggered suspension of her account was deleted.

Twitter said Thursdsay morning McGowan's account was temporarily suspended because of a tweet that published a private phone number.

"We have been in touch with Ms. McGowan's team. We want to explain that her account was temporarily locked because one of her Tweets included a private phone number, which violates of our Terms of Service. The Tweet was removed and her account has been unlocked," Twitter said.

"We will be clearer about these policies and decisions in the future. 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."

In addition to denouncing Weinstein, McGowan has been especially critical of Affleck.

In one tweet from Oct. 10, she told Affleck to "fuck off," and in another, she suggested the actor knew about Weinstein's behavior.

"@benaffleck ‘GODDAMNIT! I TOLD HIM TO STOP DOING THAT' you said that to my face. The press conf I was made to go to after assault. You lie," McGowan said in another tweet.
