I actually agree with steps 1-3, with some caveats:

I actually think curation should be 75-25 in favor of curators. Gives more incentive to own steem power, something we need more of.

Get rid of the free downvotes, there is a reason that facebook doesn't have dislike buttons, nobody wants to be around things that make them feel badly, and downvotes cause negative emotions no matter how you slice it, plus they get abused.

I actually think bid bots are good but only if they don't provide a profit to the user. There needs to be a monetary cost to promote. It can be a very small cost, but it has to be a cost of some sorts, it shouldn't be break-even and it can't be at a profit for the purchaser.

That would be a good start I think...

The good stuff likely involves price manipulation I am guessing? Something that regulators are now watching. It was much easier to pump a coin in 2016 or 2017 then it is now in 2019.
