@mastodonmigration @Bam @mekkaokereke Some people prefer to keep their posts to a closed group of people instead of publishing everything for the world to see. This could be because they don't want their employer to see what they write online, or because they're from a vulnerable group that's at risk of receiving harassment online, or because they don't want their thoughts to be recorded on the internet forever. It's a fairly popular method of posting on Mastodon.
