I am completely against this blacklisting and whitelisting business. Assume if on BTC network - some addresses are declared as blacklisted. This is censoring and is against the ethos of decentralization and free speech.
Some powerful people, having their own views on what is right and what is wrong, decide to declare others right and wrong is a way to rule others.
A blacklist as it functions here doesn't censor, the term is probably a misnomer. It's a way that a user can mark to himself and potentially others that an account should be viewed with caution.
Anybody can make the blacklist but at the end blacklists made by powerful holders are visible and seen genuine. Effectively giving authority to large holders to punish small players as is already seen with existing blacklists.
This idea actually reduces the power of the existing blacklists, by making them "opt-in" instead of making them "automatic" for everyone.
let's hope it helps. In any case I see the space evolving. I believe there will be many more iterations of similar hardforks as happened from steem to hive till a system that is useful and just for all stakeholders evolves. I won't quit but keep voicing
