I have been searching the site with a few keywords, to get an idea on unsourced and potentially libellous things. For example, 'embezzled' gets 120 or so hits, with a small percentage of some concern.
Some findings:
Embezzler: [[Lawrence King]] was uncategorised, serious allegations not sourced
Embezzled
-[[Mary Manin Morrissey]] - poor writing
-[[Miami-Dade County Public Schools]] - unsourced story
- [[Megatech]], [[Anwar Ibrahim]] unsourced about Indonesian corruption
-[[Jonathan Moyo]]
Nothing was ever proved: [[La Costa]] had a massive copyvio
Nothing was ever proven: [[Know Talent]]
Uncategorised: [[Teamstergate]] had no category.
