Rose is one of a host of stars who allege the disgraced movie mogul sexually harassed or assaulted them, and had been using Twitter to denounce those she viewed as complicit in protecting him.
Actress Kerry Washington shared her support of the #WomenBoycottTwitter movement, writing: "Starts now".
Using the hashtag #WomenBoycottTwitter, female Twitter users (along with many male ones) announced that they would stay off the platform tomorrow in solidarity with McGowan.
Twitter also played a role in the recent controversy over ESPN reporter Jemele Hill, who was suspended from her job for violating ESPN's social media guidelines a second time with her tweets about National Football League protests.
Her Twitter account, where she has been the most active and outspoken, was temporarily suspended this week, and while Twitter says it was because one of her tweets violated the site's terms by including a private phone number, McGowan has suggested that it has to do with her calling out Weinstein. But many social media users felt she had been silenced. This happened after Rose had tweeted several times this week about Weinstein and about Ben Affleck. "Not even joking, his account lives".
It additionally stated that McGowan's account would be reinstated after 12 hours, which could be hastened by deleting the offending tweets.
Countless people took to Twitter to express their outrage over what some thought to be an attempt by the social media platform to silence women speaking out against alleged abuse, while allowing powerful men's spewing of hate and violence to go unchecked.
Others, including director Ava DuVernay, suggested non-white women in similar positions had frequently not received the same level of support. She was suspended from sending tweets, retweets and liking messages, though her account remained visible to users.
