Hijacking threads is not the mature way to recruit new players. I don't want to hear who started it. It's not mature and leads a bad example for new people. I've read UC's recruitment post and it states that UC are not asshats and that they are peaceful, yet this behavior you are showing does not strike me as peaceful, it strikes me as confrontational actually. I'm neither AF nor UC and have no PRESENT alliances with either, but this paints a dull picture of UC.
If I were new, I would read this and look somewhere else besides UC to join. Take a step back and read it yourself. You will see what I'm trying to convey here.
I hope your leader will put his foot down, stand tall and tell you guys to behave. I will watch your leader and see what kind of guidance he gives to you before approaching you guys with any business from my federation.
