I wondered if you were thinking of pubs. 'England' then? (Prostitution, just not brothels or pimping or other 'organisation' is legal here.) OnlyFans is, afaik, 'a thing' here.

(But I don't use it or Instagram so I'm only really aware of it from non-UK specific stuff online. But then, if I am so are others, and some percentage of us that are aware of it presumably end up using it?)
