Hello!
I agree with you and completely understand your frustration. I'm a newbie Steemit user. It's been almost a week and so far, it seems to me that the plagiarism and spamming is a general problem in Steemit, which unfortunately keeps it from being a powerful alternative platform where most of the people creates high-quality content.
I wrote a suggestion about this issue and would like to hear from you guys. Let me know what you think. You can read it from here

Have a good one!
