Rose McGowan claims that “powerful forces are at work” to silence her from speaking out, following her suspension from Twitter.

The proud progressive actress revealed on Instagram late Wednesday that Twitter suspended her account for violating its rules. She has been using the image-sharing platform to speak out on the sexual harassment allegations against Harvey Weinstein, whom she says she settled with in 1997.

“Twitter has suspended me,” she revealed. “There are powerful forces at work. Be my voice.”

Fellow actress Jessica Chastain was among the first to relay McGowan’s suspension to her audience on Twitter, demanding to know what rules she had broken.

Earlier on Tuesday, McGowan called out Ben Affleck after he claimed to have no knowledge of Harvey Weinstein’s alleged proclivities. She denounced him as a liar and told him to “fuck off,” encouraging her followers to sign a petition to dissolve the board at The Weinstein Company. She alleges that the entire cohort had intimate knowledge of his behavior and were complicit in enabling him.

The actress also expressed her support for Harvey Weinstein’s accusers, including Asia Argento, and spoke highly of Ronan Farrow for his work in The New Yorker, which included a taped recording of Weinstein bullying a female model who refused to be alone with him in private.

According to Twitter’s terms of use, the platform is obliged to “suspend an account if it has been reported to us as violating our Rules surrounding abuse. When an account engaged in abusive behavior, like sending threats to others or impersonating other accounts, we may suspend it temporarily or, in some cases, permanently.”

Although not permanently banned, Twitter suspended McGowan from posting anything for 12 hours, providing no details on what rules she supposedly broke.
