I want to know how she found out her house was used to do porn in the vast sea of porn on the internet.
The dogsitter had advertised for her OF on social media (presumably Twitter), the woman saw that (recognizing her “unique bathroom tile”) then signed up for her OF, paying the membership fee.
The irony is, the homeowner would probably be the only person on the planet to recognize the location as her home. Now it is on national/ international news and social media. Maybe sometimes it’s better to keep such matters discreet, and simply fire the dogsitter, and insist she take the videos down, or face legal action.
