this comes from the aptly named "project mayhem"

Project Mayhem has released its first working paper on statistical and factual anomalies in silver ETFs. The conclusion is distrubing:

During our research into the inventory lists of the iShares SLV and London-based ETFS physical silver funds, we discovered multiple anomalies which cannot be easily dismissed. These included the presence of internal duplicates, rough internal duplicates, weight duplicates, statistical clustering, and cross-reference duplicates. Taken together, these anomalies are cause for concern, and we suggest that more capable teams conduct further research into these issues, as they effect price discovery within the precious metals market, as these ETF shares are being used for settlement and possibly pricesuppression on the COMEX.

If these problems are caused by accounting errors, they are disturbing and perhaps profoundly incompetent, and we suggest both these funds should have their senior management replaced.

In our opinions, the only way for all of these anomalies to occur together as noted in this paper, is via systemic fraud or gross accounting error bordering on jaw-dropping incompetence.
