I can only talk about Hungary, but there is virtually none. Where i live the victims of sex trafficking are overwhelmingli Romani girls and the cases i mentioned are the only ones that ever get reported. As you can imagine these people are mostly very poor and marginalized so no one really cares about it apart from the usual "yeah it sucks that happens, but..." bullshit.
Every once in a while these trafficking bands get busted and when it happens here, even though prostitution is illegal, if they are forced into it, cops don't harass them any further as your article suggests. Though what happens next to these girls is foggy, since there is an institutional abyss in this area so most of them end up as a streetwalker anyway where cops are way less lenient.
