I'm still amazed at how Reddit weaponized the block feature.
If you block someone, you not only can't see their posts, but you ice them out from replying in the rest of the thread.
In the past “block” used to mean what “mute” means now: Hide from me. I believe it’s around the time Twitter became popular that the meaning has shifted to being a bi-directional mute.
I find that the need for a blocking system as that just points to a broken moderation system, and a broken society at large.
