you said it is not about rewards, you wanted a solution.
A lot of people tried to present you with few, you ignored it.
One of the biggest developers wrote few "essays" of how it works and what could you do. and only thing you got from it is "Blocktrades even suggested I leave social media as a whole." and even that you misquoted (misunderstood).
I am not sure what you expected (i asked, you ignored it). Did you expected witnesses taking bernies stake? Censoring him on a blockchain level? The solution is here, you can mute him, you can make your community and not show his comments. Anything else is not possible. Because if it was, well some day it would happen to you.
All big accounts could vote your posts, but you would still leave because that would not block his comments and it is not about rewards.
I really want to know what you thought could be a solution to this situation? I know i will not get any answer from you, and that is ok, it is your choice.
Best of luck, and don't get canceled.
