No, like I said I haven't lost any friendship over it, just was unable to enjoy the game together because they've lost interest as a consequence of my playing style.
But read the OP, read what other people have posted in favor of reporting a friend, you think they care enough about the friendship to keep it going once they find out their friend is an RMT gil buyer? I don't think they are, at least a good majority of them would probably shun you out of their lives over a game!!
So many people on a high horse over their internet conduct, life is not all black and white, I know it sounds cliche but it's true.
When talking about ethics and morality, I really have a hard time accepting such rigid points of view. Unless you've done some serious soul searching and come to grips with the reality enough to know what school of ethics you believe in, don't be surprised if I don't take your view seriously.
It's easy to see the World as black and white when you have a very narrow spectrum, but once you widen that with experience, you'll see how little you really know, that's true of just about everything.
A high school student of Physics may believe that objects fall at 9.81m/s^2.
A college freshman may learn to believe that the acceleration due to gravity shifts depending on elevation and use a more complex equation.
A college senior may once again adapt even more variables to the equation because gravity exists between all objects and may explore situations where it's not always on Earth.
Then a Grad student may skip the Newtonian interpretation altogether.
Remember when you were little and you thought Algebra was the highest form of Mathematics there was? Then as you took more advanced courses, how trivial it really was and how little you actually knew about Math?
Not everything can be solved with X, Y, and Z and most of these people seem to be prescribing a simple treatment to a much more complex problem.
I do sincerely hope all the people holding their black and white views on this come from an educated perspective and that it doesn't stem from one's own naivety and simplifying a much more complex problem.
I have done that before, so I've learned from it. Although I did not lose a friendship over it, I found it less enjoyable to be playing the game alone.. If I found my friend was doing something immoral, yes I would in fact, confront him about it and try to make him see why he is wrong. But I will definitely pick my battles carefully, and this is simply not one of them. I'll still mention it that he stands to get banned from the game etc. etc. But really, I'm not going to have an intervention over this. I've bigger things to worry about.
