You probably heard it... the Goons are running and Ice interdiction again.
Let's look at what happened:
a) "Random Internet Space Pixel Emperor" (The Mittani) announces Ice interdiction.
b) Prices spike.
c) People sell their stocks.
That is all the relevant stuff. Not a single thing more was required to make the interdiction a success. There might be some aftershocks to prices once stocks deplete, but that would be speculation to go with. The sure made profit is and has been made.
Here's some stuff not at all relevant for the success of the Interdiction.
a) The amount of miners actually killed.
b) Creating a shortage of specific Ice.
c) The amount of roaming Goons in HiSec. (Although a few stub fleets flying around will make "the next interdiction" more likely to succeed).
And here is some stuff that is likely to be a "bonus" on a couple of levels:
a) People flying in cheap fleets ganking for "fun" or tension release.
b) Creating "fear" in people, upping chances for success of next project.
c) Upholding the "myth" of the Goons power.
Basically, the entire Interdiction had three phases, of which two are already completed: Loading, Firing and Reloading.
Loading: Setting up the Interdiction by stockpiling Ice.
Firing: Announcing the Interdiction, causing fear, speculation, greed and a multitude of other factors to rise prices.
Reloading: Actually "doing" the interdiction. By no means like announced, but on a more subtle level: You don't need to actually dent Ice volumes at all, it's just an added bonus. The more you can dent it, the better the after effects of the Interdiction (making it possible to do it again), but it's by no means a requirement. The important thing is to kill a few miners here and there, keeping up a couple of roaming gank squads, and if you want to pepper it maybe fake some killboards with alt miners that get ganked to create the impression of something actually happening. With the Goons manpower, this doesn't really require a lot because it'll be a self runner.
The last phase, which is currently running, is a lot about perceived force and its projection. It is more than enough to create a wide spread impression of being active, no need to waste resources actually doing so.
All in all: Median Nitrogen prices have gone from around 580 to 960 and higher.
It'll be interesting to see what further media coverage will do and how the Goon Meta- Team will exploit the unfolding events for future use.
