To me what we need the most is for 1, members do not see the comments of those who have blocked them or been blocked by them, and 2, members cannot ping members they have blocked or been blocked by.
Ive noticed many members cause a storm before getting moderated because of the time it can take moderators to take action, and people in the feed see stuff happen in almost a few minutes, so it can cause a chain of members causing problems, and I know there are people who cause problems, and they have chains and chains of friends who let the problems roll across them to the next person like a conveyor belt, and at the end of those problems moving across member by member it falls right back on the person who is accused.
Better Blocking features
However for example, You are Member 1, And There is Member 2, who has blocked you,
Member 1 is looking at wallpost and they see that somebody has shared a wallpost of Member 2,
Member 1 cannot see Member 2's wallpost but they know that it was shared, Member 1 keeps scrolling and they can actually see member 2's wallpost, they and their friends decided to copy and paste part of the wallpost and they post it on their profile.
I think PMC would be much better if blocked members could not see Your post, replies, and the rest of your actions on pmc, infact it may be even better if you could not even view comments of who you have blocked.
This was inspired by recent events and conflict caused by a group of members targeting the wallpost of a member who had half of them blocked, infact the ones they did block were the ones who were the first to do this action,
I believe none of the conflict would have happened if Both members had never seen eachothers post.
