Fine, but the stuff being complained about happened in the 1960s and 1970s. In any case, ownership by a corporation does not imply that age must be checked, to my knowledge. Many churches are incorporated for example, but checking the age of churchgoers on entry to a church seems as if it would be unusual. If you think age should be checked, you need to state clearly the legal reason why. For example, is the establishment a licensed bar in which alcohol is served? just that sex goes on somewhere in a privately owned or rented residence, or that a building in which sex sometimes occurs is owned by a corporation (eg hotel owned by Holiday Inn) does not seem legally sufficient to mandate an age check by guards at property perimeters.
Yes.
