for instance you and a friend don't like someone you blacklist that person and then go ahead and tell your friends to blacklist that person
VOLUNTARY blacklists are used to mitigate harassment and help filter out boring content (spam).
It's just like setting a spam filter on your email, if someone is harassing you, you just filter them.
It doesn't "do anything" (scarlet letter/black mark) to the "bad" person, unless you VOLUNTARILY join (subscribe to) a blacklist that happens to have that person on that list.
For example, if this proposal goes through, the first thing I'll do is UNSUBSCRIBE from marky's vigilante BS blacklist.
Thanks for explaining abit more 🤝
