Well, JaggerRiver, I've got an private message from General Kanabis today, in which I read, that I should declare peace with you, because you became aligned with New Sith Order. And so I did.
I can only speak for myself, and therefore, I can't tell you why Caspase and Celtucis continue their raid against your nation, since I assume that they got a message from the Mandarin too.
You're also asking why no one has stopped us yet. Why? Because no one gives a sh*t about unaligned nations. Everyday, raiding occurs against such nations, and while some alliances prevent their members from raiding, others don't and they are always looking to find targets like you. We in COBRA are not special compared to others.
The only difference is that while most raided targets eventually settle into an alliance of their own suiting, and learn from their experience, then there's you, who dares to b*tch about it, expecting anyone would rally up to you as your personal bannermen. I've bet if Keemstar ever cared about cybernations, you could easily claim your 15 min. of fame in Drama Alert.
