I have a friend OOC who heard me talking about Eve and became a player. Although his character would have had very little reason to interact with Saxon, I took him into my corp because I knew him OOC and he asked me to OOC. BIG MISTAKE.
His RP proved to be wholly incompatible with what we were trying to do with the ILF and when I called him on it, he staged a mutiny and took most of our best combat pilots with him.
IC, Saxon has always taken the stance that if someone leaves it is the path they are meant to follow. He doesn't hold too many grudges and focuses doggedly on moving the corp toward its goal of a safe and prosperous Intaki.
However, it was hard not to be mad at him OOC, especially when I learned that months after he left he was continuously trying to poach my corp members, all the while denying it when we met OOC.
If he had said to me, "That's the way my character is and he's going to be underhanded" then maybe I could have looked at differently, but he would say "Hey, we're friends, I would never do that to you." and then someone would send me a chat log where he was saying "Saxon is a fool, NRDS doesn't work, come fly with us, blah blah blah."
The OOC douchebaggery was really too much and now I have very little to do with the guy.
