It is easy to corrupt nations with a lot corruption. If it intgty is above 90% it is very hard to corrupt a nation.
This doesn't mean anything in-game.
At any rate, cool it. I understand you have a goal/aspiration, but other people don't telepathically know what your goals are unless you tell them - which you now have - but even if you do, they're not obligated to help you achieve them. If you have an issue with someone, you bring it to me and I'll see if I can help work things out, but as far as I can tell for the moment, you've been unnecessarily abrasive when Epiree had no reason to know that there was a problem.
I'm not imposing any penalties as yet, but if you keep up the hostile attitude, I'll see about 'muting' (read: suppressing all posts because I can't technically impose a mute) your RMB posts for a day. This is supposed to be a friendly, welcoming place, not one where you take out your aggression or anger on other people.
Tl;dr: lay off Epiree for something they didn't even know was a problem, and stop making threats in general.
