Which one?
I don't see any "Investigation" board except this one

https://bitcointalk.org/index.php?board=227.0Usually, you post there if you don't have any concrete evidence and you want to gather more information about a project, specific user etc.
You don't start a Scam Accusation topic based on speculations only, at least that's what I think...
Anyway, thanks for the nltimes link - it was a good read.
