If there are no active mods in a subreddit someone can go to /r/redditrequest and get it back. If you own a subreddit the best thing to do is private it with only you as moderator, and maybe post a comment every two weeks or so, so you count as “active”
I had a small subreddit, I just set it to private, removed all the other mods and then removed myself as mod. fuck reddit
