@terryenglish @r000t I'm in agreement witih Terry here.
What I was going to say:
I certainly would never deploy or use such a system. Strongly worded, but let me explain:
A system that takes these VERY IMPORTANT choices out of the users hands is pure evil.
At best I could imagine something like "Here's some instance blocks we think you'd enjoy".
But in all honesty, I think such a system is an ideal tool for people to a) abuse, and b) unwary ones to shoot themselves in the foot with.
Automatic censorship is something very dangerous, I believe.
People should have the opportunity to be able to change their minds the very next day. A instance blocklist, hidden ten clicks away in settings, hinders that greatly.
I think technology should only ever be used to connect people, not wall them off.
Just my two cents.
