I don't mind the shitposts with low rewards, bad content is everywhere on the internet, unfortunately it must be here too. However, my largest issue with steemit is seeing shitposts with 100-200$ rewards. How can a platform succeed if that kind of behavior is tolerated here. In the long run it brings more bad players into the system and steemit could fail miserably because of that.
And that's something that we can't avoid. Many things depend on human morality and honesty, since all is allowed.
