That being said, if a provider chooses to offer it there is nothing I, or you or anyone else, can do about it, and shaming them wont change a damned thing. As for client risk, sex outside of monogamy is always a risk, you could just as easily pick something up from a girl who doesn't offer BBFS but has BB sex with her spouse who passed something on to her, or a civie, or whatever. If you're worried, use protection, or don't hobby.
As for your second question, I already said I don't necessarily condone the public outing, I think there are other solutions such as private lounges and websites like verifyhim which are absolutely necessary and should be used. Blacklisting is paramount to provider safety!
