New posters on the London Underground are calling for the decriminalisation of sex work, as part of an adhacking campaign that comes simultaneous with a sex worker strike for International Women’s Day.

“Why is using sex to sell OK and selling sex isn’t?” asks one poster, shared on Twitter by Revolting Prostitutes: The Fight for Sex Workers’ Rights author Molly Smith, alongside images of a demonstration by activists in red veils.

Tube posters shared by another user, which are attributed to the English Collective of Prostitutes, read, “Most sex workers are mothers supporting families. Outlaw poverty not prostitutes”, and “Two thirds of sex workers have suffered violence. Decriminalise sex work. Safety first”.

Both sets of posters bear the #decrimnow slogan.
