Rose McGowan, one of the first women to be named as a victim in the Harvey Weinstein sex abuse scandal, was briefly suspended by Twitter after commenting on the controversy.
The 44-year-old actress, who has been a prominent figure in the controversy engulfing Hollywood after she was named alongside Ashley Judd in a New York Times expose last week, said "powerful forces" were behind the block.
On Thursday Twitter reinstated her account and said it had been suspended for posting a private number in a now-deleted tweet.
According to the New York Times, she had received $100,000 from Weinstein after an encounter with the producer in a hotel room during Sundance Film Festival in 1997.
McGowan didn't speak to the publication, but praised its journalists, Jodi Kantor and Megan Twohey "for [their] incredible work".
Since then, she has used Twitter to comment on the controversy, praise women coming forward and call out those she believes should have done more to expose the producer's actions.

On Wednesday night, she wrote on Instagram: "TWITTER HAS SUSPENDED ME. THERE ARE POWERFUL FORCES AT WORK. BE MY VOICE. #ROSEARMY"
She also posted an apparent notice from Twitter that read: "We have determined that this account violated the Twitter rules, so we've temporarily limited some of your account features."
In a series of tweets on Wednesday, Twitter said it had reinstated the account.
"We want to explain that her account was temporarily locked because one of her Tweets included a private phone number, which violates our Terms of Service," it said.
"Twitter is proud to empower and support the voices on our platform, especially those that speak truth to power."

McGowan, who has spoken out in the past about rape and harassment issues, has used Twitter to call for the board of the Weinstein Company to be dissolved following the allegations against its co-founder.
The actress tweeted a link to the campaign on website ipetitions.com and said: "Join me in supporting this important cause at iPetitions. DISSOLVE THE BOARD."
More than 10,500 signatures had been added to the petition by Thursday morning.
She also called out Ben Affleck, accusing the actor of lying after issuing a statement that he was "saddened and angry" about the Weinstein revelations.
McGowan suggested Affleck knew decades ago about Weinstein's behaviour.
