Following Rose McGowan’s temporary suspension from Twitter, a number of notable figures in Hollywood have supported the #WomenBoycottTwitter protest on Friday in solidarity with women whose voices have been silenced.

Though McGowan has been vocal on Twitter against Harvey Weinstein, who she alleges raped her 20 years ago, the social media company said her account was suspended for 12 hours because one of her tweets included a private phone number, which violates Twitter’s Terms of Service.

Before the day-long Twitter protest began, celebrities spoke out in unity with McGowan and the dozens of women who have come forward with their stories of Weinstein involving sexual harassment or assault. McGowan kicked off the boycott writing, “At midnight we RISE.” Kerry Washington joined in shortly after, saying, “Starts now.”

Ava DuVernay, however, noted that women of color haven’t received the same support when speaking out. “Calling white women allies to recognize conflict of #WomenBoycottTwitter for women of color who haven’t received support on similar issues,” she wrote.

“Ladies. Let’s do this. #WomenBoycottTwitter. Not because of hate but because I love this platform and know it can be better,” Chrissy Teigen wrote, while Elizabeth Banks said, “Taking a mental health break from Twitter.”

McGowan encouraged men to stay on Twitter and amplify their voices, writing, “Call on your brothers to be better, go after ones who won’t.”

A number of men got in on the movement as well. Mark Ruffalo tweeted, “Tomorrow I follow the women,” while Nick Offerman wrote,”I’m with her (ad infinitum).” Questlove urged people to back Jemele Hill, who was recently suspended from ESPN over her social media usage. “In addition to supporting the #WomenBoycottTwitter movement I ask you all, remember that [Jemele Hill] is catching hell as well.”
