Used to categorize in Category:Copyright violations suspected and put a box on the entry page, as shown above.
A first positional parameter if any is displayed in the box: this is meant for specific information (e.g., what part of the entry is suspect, or where it might have been copied from). If the text to be displayed (the value of the parameter) contains an equal sign then use |1=the text
, thus:
{{copyvio suspected|1=Looks like it was copied from http://example.com/?foo=bar}}
