These articles are aimed at the dudes who book on all these classified ads and don't do their researches. Behind them (the law and these peoples behind the campaigns) i think there is good intentions. I wouldn't want to book someone that is exploited either. Of course they can't do it, but they should have "Johns" to explain in articles actually why they are doing this at all. But at least they should open the mic more toward providers and not just the ones who got out of it and were exploited.
Anyway, as some pointed out, every year toward GP its always the same thing, they flex muscle and try to scare clients. Personally i let the tourist have their fun during this event. Im not at all into F1, i don't want to overcomplicate things for myself (aka harder to book due to demand) and well... thats it.
I know some women are exploited, i know dirty pimps exist, i know minors are involved too and some dirtybag look for them. Showing me all of this wouldn't change my view. Its like showing pictures from a gun shooting to a hunter who buy a gun... I personally book in reputed agencies or with reputed indies, with providers who do this on their free will. I see no harm in it. Its an exchange of services just like anything else.
