self published and questionable sources about themselves an important lesson from wikipedia and i quote self published and questionable sources may only be used as sources about themselves and only if the material used is relevant to the notability of the subject being discussed it is not contentious it is not unduly self serving it does not involve claims about third parties it does not involve claims about events not directly related to the subject there is no reasonable doubt as to who authored it the article is not based primarily on such sources emphasis mine tiger by the tail
