they shut down a LOT of boards, VXX, DGAZ, etc. i shares boards. this one will probably go soon. been reading the boards since 2006 or so and when you filter thru the nonsense, you do get some good ideas, hints and helps
I wonder why though. The messages on GDXJ were generally on subject compared to the many other spammy boards. As a side note, you can still directly access the GDXJ board from url or by using "get message board for:" function.
Always go with the conspiracy theory. SEC probably noticed some messages were tied to stock manipulation and asked Yahoo where they are coming from. Yahoo had to disconnect it to download the data. Makes sense: Why would GDXJ drop so many days when GDX and GLD were going up?
