Okay, I've been trying to think of a scholarly answer for why the IGS pisses me off in general. So, I'm gonna give it my best attempt, now that the pizza and booze had thoroughly soaked into my brain-parts...
In my opinion, the IGS was either meant to be, or simply should be from my point of view, a reactionary entity. It should essentially function as a subordinate counterpart to the in-game universe. Case in point, if I were the head of my own corporation, and Senn's IC intention was to dismantle a loyal Federation corp, I would start targeting that corp wherever I saw them. After a few weeks of picking off targets, someone would likely notice they were dying to the same corp tag repeatedly.
THEN, the targeted corp would have a reason to hop onto the IGS, and call me out. This serves the purpose of unveiling my attacks, thereby calling that person's allies (if any) to action. I could make a reply if I wanted, or stay silent. As the events in-game escalated, the IGS would respond in kind, and when the conflict died out, so would the news about my corp's attacks.
Instead, what I see is one corp's leader calling out another's due to some inane reason, or one player swearing fealty to a corp/faction as loudly and insultingly as possible to any potential rivals/enemies. This results in a glove-slapping whirlwind of personal attacks, character assassination and whining.
THEN, because of all the hate on the IGS, someone starts trying to target someone else. They're solely reacting, and so essentially have made themselves subservient to whatever the IGS' general consensus is on the battle in question.
Its entirely backwards, and its causing more problems than a forum is worth.
