In the weeks since Harvey Weinstein’s history of alleged sexual assault came to light, many have gone public with their own experiences, whether it’s stars like Gwyneth Paltrow and Cara Delevingne sharing their stories of Weinstein’s abuse, or women from other industries speaking out about harassment in their own fields.

Sunday night, Twitter and Facebook lit up with sexual assault testimonies from women and men around the world, following actress and activist Alyssa Milano’s call for survivors to tweet the #MeToo hashtag to illustrate the “magnitude of the problem.” According to Milano, the idea was suggested by a friend. She wrote, “If you’ve been sexually harassed or assaulted write ‘me too’ as a reply to this tweet.”

As of Monday morning, tens of thousands have replied to Milano’s call alone, with many more sharing their stories in individual posts.

Lady Gaga has spoken out about her experiences as a rape survivor before, including cowriting and recording the song “Til It Happens to You” about her ordeal.

Gabrielle Union is an advocate for sexual assault victims and spoke out about her own experiences in 2016.

Comedian and political satirist Barry Crimmins joined in with his experiences too, adding his voice as a male assault survivor.

True Blood star Anna Paquin responded with a simple “Me Too.”

Hamilton actor Javier Muñoz, who has been open about his sexual orientation and his HIV-positive status, added his experiences as well.

Patricia Arquette contributed too—just days earlier, the actress spoke about a “weird” encounter she had with director Oliver Stone.

Debra Messing stuck to the simple two-word reply.

Rosario Dawson pointed out how pervasive sexual assault is.

Evan Rachel Wood wrote candidly about how her image as a “party girl” made her feel like she “deserved” her experience.
