How to treat posting spam advertisements and sending spam messages advertisements?

The first impression people get from those who advertise and post advertisements at will is not the regular products of the merchants, but the deceptive products. I hate them very much. I never buy those products or invite those people to do things. These businesses that don't even have a basic sense of public morality are very boring or boring. There is no right way to promote your products and services, and you don't have to post them door to door. It is suggested to set up a free advertising column at the entrance of the community, and post flyers in the advertising column. People who need it can go to the advertising column to find the advertisements they need.
