I don’t really have questions about OF beyond getting context for the billboard. In the US I don’t see porn stars advertising in such everyday places. I have certainly seen billboards that are similar to the one shown in this article, but those are from companies with a big advertising budget like Victoria’s Secret, as you mention. I think porn stars are generally not wealthy enough to have a big advertising budget for billboards.

I’m ignorant about what content OnlyFans has. Is the woman on the billboard a porn star?

Does xlwings require any specific Python installation? Can I use it with my WinPython 3.10 installation on Windows 10?
