What does it mean to put up a yellow gambling slogan in front of the apartment?

According to Baidu, the slogan posted in front of the apartment means to crack down on pornography, cherish family, cherish life and stay away from pornography.

Slogans not only have accurate and concise stylistic features of official documents, but also have rigorous and inspiring stylistic features of political discourse. They can not only enlighten people intellectually, but also impress people emotionally, shoulder the mission of social education, play a guiding role in influencing social public opinion and cultural communication, and reflect the essence of social economic system and the degree of social civilization to a certain extent.
