Wikipedia:Disruptive editing

Disruptive editing is a pattern of editing that disrupts progress toward improving an article or building the encyclopedia. The editing pattern may extend over a long time on many articles. Disruptive editing is not always vandalism, though vandalism is always disruptive. Each case should be treated independently, taking into consideration whether or not the actions violate Wikipedia's policies and guidelines. If an editor treats potentially disruptive situations as acts of vandalism when it's unclear or when it clearly isn't, that editor may harm the encyclopedia by alienating or driving away others from contributing. This is especially true if the situation involves editors who are new to the project.

Disruptive editing is not always intentional. Editors may be accidentally disruptive because they don't understand how to correctly edit, or because they lack the social skills or competence necessary to work collaboratively. The fact that the disruption occurs in good faith does not change the fact that it is harmful to Wikipedia.
