Your entire premise that downvoting is “violence” and needs some kind of solution is flawed.
First of all, a downvote is not violence. It is not theft. It is not like rape (as some have argued in the past). It’s simply a downvote...no more “violent” or “abusive” than an upvote. Rewards that are allocated to your post during the seven-day voting period are not yours. They become yours once it closes - then it cannot be stolen from you unless you’ve been phished or hacked.
Secondly, as others have explained here and in the past (including Dan Larimer), you cannot disallow downvoting in a system where downvoting is the only real check against gaming the rewards system. If you eliminate downvotes (whether directly by protocol or by “blocking” them through individual profile functions), then you actually eliminate abuse mitigation. This was something that Dan had struggled with and admittedly could not resolve (as of two years ago - I haven’t seen him speak about it since then).
And finally, this is a DPoS blockchain. The entire system is based on ownership via shares/stake in it. It’s not a secret. There are no surprises. Nothing about it is hidden from any users. We all have a choice to begin interacting with this blockchain and to remain using it.
The underlying code and consensus protocols stipulate that those with more shares/stake in the blockchain - the people with more skin in the game - are the ones who have more control over the direction of the blockchain and its development. It’s not that different from being a shareholder in a company. And just as you can do with your stock in a company, if you’re not happy with this system, you’re actually able to do the one thing that you can’t do with real-world governments:
You can take all of your money and leave.
There’s no violence. There’s no theft/extortion. There’s no “mob.”
There are only individuals interacting according to blockchain protocols and using their own stake as they see fit. And everyone can do this.
The one caveat to all of this is:
Steemit, Inc. has severely skewed/damaged control and interaction on this blockchain due to the initial distribution of STEEM and their subsequent behavior/development since then. It is still a thorn in everyone’s side and may still take a long time to work itself out...if it ever happens.
Here, as you say, the "rules" of the game have been distorted from the beginning and you can no longer correct them. So the self-regulation of the system does not work. There is no hope ... except to consider steemit a bargain for a few users. Take or leave.
