Telling people not to flush certain items is an effort in futility. People will do what they want with impunity.
It’s like the CFL bulbs and rechargable batteries which aren’t supposed to be thrown in normal trash but are all the time.
I have a family member who bought a home in a fairly upscale part of town. A few months in he had to have his main sewer line dug-up and replaced. He discovered that the prior residents of the home (Middle Eastern types) had been flushing diapers and sanitary napkins into the line for years.
