First: block all accounts at Steemit/Steem blockchain and the only way to get unblocked is by taking a course in "How to Make More Money using a Long Term View over a Short Term View".
Second: execute the courses
Third: enable accounts again after taking the coarse, BUT in a sandbox environment - this is to test if users actually learned
Forth: allow those who passed point three to come back to Steemit
Another solution would be:
Steemit Justice and Court system with unlimited SP who can FLAG users rock bottom when they don't follow certain rules and they enforce as a minimum the rule: "Steem value shall not be harmed" and "Forst Crypto Social Network shall be there in at least Five years time".
