Since you mention the issue of multi clienting infinite afk characters in your example and your avatar says you've been playing since 2003, you should recall a time in which multi clienting was actually not allowed or possible for most players. As the basic Ragnarok exe did not have the feature until ~2007.
Do you think that player feedback / requests had anything to do with it?
I may be missing the take away from your post, but it seems like you are saying the conversation is perhaps interesting but also pointless to have. Not sure if it is just general cynicism or if you believe that nothing can / should be done. I don't think you are saying the conversation is not worth having, as you have contributed to it the most so far. It seems to me like you are more in the first camp for unrestricted afk / auto if I were to boil everything down.
Its just confusing because the ethical / morality principles you outlined for your own personal conduct seem to contradict what you would favor for being allowable. As in, just because you can run 30 clients and reflect on all of them doesn't mean you should. By that token, wouldn't you say that it would be reasonable to suggest that a line be drawn for what is allowable and what is not for the good of all players?
