I disagree. When they don’t see your posts, you might as well have gone silent or just post less frequently so they happen to not see them. Besides: once you follow a certain number of people, you don’t track each and everyone of them.
Seeing a post makes you more likely to want to answer them. If that doesn’t work (as I understand it), you will notice it and maybe be frustrated about it.
Yes, grief has to have limits otherwise it’s not healthy. You have to get over your loss and continue your life after 30min.
