The hashtag #metoo has been trending on Twitter this week. Why? In a show of solidarity, tens of thousands ofwomen (and men) have been tweeting toreveal that they, too, have been victims of sexual harassment or assault.

Since many celebs, includingCara Delevingne, Gwyneth Paltrow, Angelina Jolie and Rose McGowan,have been coming forward with allegations of sexual harassment and assault by big-time Hollywood producer Harvey Weinstein, the topic has been a big one on Twitter.

This week, #MeToo provedthat sexual assault and harassment is not unique to Hollywood -it's actually an epidemic. The trend kicked off when American actress Alyssa Milano tweeted this:

When Rose McGowan (Alyssa’s fellow cast member in the series 'Charmed')was recently banned from Twitter for abusing its code of conduct allegedly in the way sheaccused Ben Affleck of knowing about the Weinstein scandal, people were calling all women to boycott Twitter for failing to support victims of sexual assault. But there were mixed reactions, as some people thought women boycotting Twitter would just silence female voices even more on the subject.

This new hashtag seems to make a lot of sense though, and with more than 30,000 women (and some men) using the hashtag to add their voice to the masses, it really does show that sexual assault and harassment is still a widespread problem.

Some celebs have been using the hashtag too, with'Skins'actress Kaya Scodelario coming forward after years of silence to reveal thatshe's experienced the same thing:

It’s great that so many women are finally speaking up in relation to the sexual harassment and assault by Harvey Weinstein that went on for decadesbut, as this Twitter trend shows, Weinsteinreally does seem to be just the tip of the iceberg.

We love that this hashtag meanssticking up for every woman who's been sexually harassed or assaulted, and that Twitter is being used as a platform to place the blame on the perpetrators, NOT the victims.
