First of all, thank you for your efforts. I appreciate it!

But how much does that user drain from the system in a given year? The reward that's paid to the authors and curators in a year amounts to $65 Million USD a year! What's the share of that user in that reward?

How much of that reward is paid to the posts and curators that didn't deserve it in the first place?

Suppose that we eliminate that user. What's going to happen then? Will the abuse problem finish?

The ROI of abuse is the same if you have a huge stake or a minimum stake. What's the difference between a person stealing a million USD and hundred thousand people stealing ten USD?

I doubt that we can fight the abuse by focusing on single cases.

The only way we can prevent the abuse is to get rid of the reward system for authors and curators and to introduce the tipping system for posts and authors. Otherwise, with this scale of cash bleeding, the Steemit ecosystem won't last long.
