Harassment is a pattern of repeated offensive behavior that appears to a reasonable observer to intentionally target a specific person or persons. Usually, the purpose is to make the target feel threatened or intimidated, and the outcome may be to make editing Wikipedia unpleasant for the target, to undermine, frighten, or discourage them from editing.

Wikipedia must never be misused to harass anyone, whether or not the subject of the harassment is an editor here. Edits constituting harassment will be reverted, deleted, or suppressed, as appropriate, and editors who engage in harassment are subject to blocking and banning.

Harassment can include actions calculated to be noticed by the target and clearly suggestive of targeting them, even when no direct communication takes place.
