Is it possible to eliminate bad and unwanted behavior in any society, digital or not? Absolutely not. Does that mean we should not try, fire the people who should maintain order and descend into anarchy? I would hope not.
I think there is a very delicate balance we should strike here at Steemit because at other social media sites free speech has been stymied in some form or another and it has always started with "good intentions".
Herein lies the problem. Spam is wrong, copyright infringement is wrong, etc, etc...and we want to fight it but I don't think it will ever be completely eliminated nor should we be discouraged if it isn't because its an impossible task. Think of the War on Drugs.
I think people like you should continue doing what you do and if you get tired pass the ball to somebody else. We thank you for your efforts! This war will continually be waged and it will always be a standoff and perhaps should be.
