I guess this is the result of all the mean spiritedness in the game itself. I'm a skiller who has had a fair share of insults thrown at me for no particular reason or for simply having the superior internet connection and pickaxe. Eventually, I got tired of sharing because there was no courtesy from the majority of players who I offered to share with, much less any form of gratitude. So yes, I mine all the iron I can obtain without regard for any other simply because I know that if they were in my position they would be doing the exact same thing. The only real time I probably would surrender a spot over is if someone actually remembered their "P's" and "Q's" when addressing someone who has dominance over them in that particular field. A simple "Please world hop/ mine elsewhere/ share the rocks." would be more than enough to get me to agree rather than the usual "PLZZZZZZZZZZZZZZZZ!!!!!!!!!!!" and "OMG GO AWAY NOOB!". In summary, be nice to the nice and cruel to the cruel. If you don't like my work philosophy, then it's okay.
