How to politely respond to people breaking a rule in forum etiquette

Hello guys! I have seen many people repling with no manners to law-breakers. I would like to tell you the Dos and Donts for repling them.

Begin by introducing them to the forums if they are a new account.
Writing in an polite informal way.
Beware your manners

Public shame them by messaging others to dislike.
Type with intentions of scolding, lecturing
Ask them to stop advertising without telling them whats wrong.
