An edit war is considered a "war" if you revert edits on an article 4 times within 36 hours.
If an article is fully protected a topic will be started by the admin who protected the article on the article's talk page to discuss the edit war.
In all situations discussion is should be the norm, not an edit war or admin action (in the form of protection or blocking).
What isn't an edit war

- Reverting or removal of breaches of our image use or video policy.
