I get what you mean, but the issue here is that there are multiple people who I would not have blocked, did not block, and don't concent to blocking that were blocked for me because of your filters I was unaware that it even happened, and I never interacted with them. That is an issue, and from my perspective that is censorship whether or not that was your intention I don't disagree with any of the point you've raised, nor do I expect perfection or a system without flaws. It's a very complex topic, but the reality is that we are looking at a slippery slope similar to past social media experiences, and several people have already been slid down it.
So until we find a way to refine a web of trust/distrust, I want to opt-out of anyone adding someone to my unlock list. I'm a big boy, I can choose for myself.
