People are so scared and cautious these days that in trying to protect their own accounts they don’t reply to anyone They fear their ID might end up in spam or that someone might get upset with them

It’s not that people don’t reply to anyone — it’s because of the spam label. If someone I’m not following leaves a comment, I don’t get notified. Unless I go into the post and check manually, I can’t see their replies.
And lately, even that has started disappearing. I’ve changed my feed settings so that all comments show and notifications are on, but sometimes their comments still don’t appear.
