You can hire anyone and have them target of allegations from colleagues. Them having a higher social status won't really help, we're post #metoo and there has been way too many cases of well regarded people being predatory. Whether the employee had some arguable past jobs, you'll have to do due diligence and get to the bottom of it either way.
1: This is location specific. You should hide it if you ever want a decent job in a smaller town.
2: It is position specific. Many public jobs or jobs in childcare, teaching, or where the company relies on its appearance in the community will not hire someone with a history of sex work in whatever form it takes, and if you hid it to begin but the truth came out you will at best receive backlash for it and at worst be immediately fired (or fired as soon as the paperwork clears).
I have nothing against sex work in any form, but our society as a whole has a strong reaction to it and it will be at least 50 years before we get over that.
