Believe it or not, we have tried to keep it simple. There is a balance between constraints and incentives.
As we designed the system, we identified each of the constraints and potential power leaks and built in the appropriate safeguards. That created levels of complexity, but it works pretty well even though hard to understand.

The most common 'complaint' we receive is when people double or triple their posting frequency to take advantage of what they think are consistent 'per-post' upvotes, and then they are shocked to see that we adjust to their posting frequency change to prevent them from robbing SP from the other members.

I think the worst I saw when somebody complained about their upvote value dropping and demanded explanation, their posting frequency had increased by more than 10x.

Most people that join to try to take advantage of our system don't have staying power when they learn that it's designed to prevent that, and they go completely inactive on Steem when they learn that it's not a get-rich-quick scheme.
