I just received a new memo from "The Whistle Blower", which was sent by email using the Tagruato email address: firstname.lastname@example.org. I had emailed them a while back asking about the ParafFun recall.
The memo itself is written in Japanese (translation anyone?), but another hand-written message reads:
Americans, No Oil Here! They must have known before they built! - The Whistle Blower
Interestingly, the memo came as a PDF, and the file name is pseunmoisuf.pdf. I Google search for pseunmoisuf doesn't turn up anything... maybe it is an anagram?
UPDATE: Kosmopol from Unfiction has provided a translation. The document is a financial statement for the third quarter of 2007, with a table of the profits from each drilling station. Conspicuously, missing from the list is the Chuai station.
