What I'd like to see, rather than virtue signalling on twitter, is people in the entertainment industry actually owning that they enable such behaviour and that they are all individually responsible for the safety of their female colleagues.
Film and TV sets are busy places. None of the behaviours Noel Clarke has been accused of - and that many other men in the industry indulge in - happens behind closed doors. From the shouting and humiliation, to the inappropriate touching, comments and demands during shooting, plenty of people would have been there to witness it. If you see something and don't say something, you're part of the problem.
I know it's difficult if you're in a junior position and you feel you need the support of powerful players to help you on your way in your career. But are people in the entertainment industry so morally bankrupt that they will happily stand by while a colleague is being shouted at and harassed in front of them? It seems many are. It defeats me why anyone would want to work in such an industry, where so many people will sell their souls and swallow their morals for a few minutes of screen time.
If they really want change, it has to start with each individual recognising that they have a role to play in changing the culture. Rather than standing by people on twitter, how about you stand by them when they're literally standing next to you in your workplace? Deeds not words!
