Can you explain what that last article has to do with MarkMonitor? To me it just sounds like MarkMonitor once bought a company from a law firm which was sued for fraud 5 years after the sale was completed. So it doesn't appear that MarkMonitor was in any way related to the fraud which occurred.

Good call out! If Schlüter didn't continue doing work for DtecNet after the sale to MarkMonitor then we can't really blame MarkMonitor for the things he was doing 5 years later.
