The civility policy is one of Wikipedia's five pillars. It is a conduct that explains how Wikipedia users should interact with each other. They must refrain from personal attacks (threats, profanity, etc.), especially in edit summaries and elsewhere on Wikipedia. Violating this policy will likely result in blocking from editing. If the user is trying to deal with incivility, they are recommended to use the target's talk page, third opinions, and request for comment on the user conduct.
