1. Audience
People who can see your post can see the audience you chose to share next to your post: Public (), Friends (+) (), Only Me () or Custom (). If you chose to use Custom to include or exclude specific people from seeing your post, then only "Custom" will show next to your post. People will not be able to see the individuals you specified.
2. Lists
If you choose to share with one of your default lists (Close Friends, Acquaintances, Restricted) or a custom list, the people on that list will be able to see the other people included on that list; however, they won’t be able to see the name of that list.
If you choose to share with one of your smart lists, the people on that list will only be able to see the name of the list.
