@kensanata@octodon.social @GeekDaddy@octodon.social People I follow and mute are people I'm considering following. I do not mute their notifications, they just dont show up in my timeline.
When I clean up accounts i look at only the muted ones and review their posts and occasionally upgrade people to an unmuted status or after a time delete them.
But yea its like a bookmark to consider them for later.
