Recruitment for this research study is done on social media. When you “post” something, only users have the power to limit what is shown to them and they can decide how they want to interact with those posts. You can always control who you share a post with, you can always control who can see the posts you are tagged in, and you can always remove tags from posts. Below are brief instructions on how to do this. If you have any further questions, please visit https://www.facebook.com/help for more guidance on these topics.
You can choose who can see your post on Facebook using audience selection.
Audience selection is available in most places where you share content on Facebook, such as posts, photos, and information on your profile.
Audience selection allows you to choose a specific audience when you post something. Your options may include:
Public : When you share something publicly, it means that anyone, including people outside of Facebook, can see it.
Friends (+ friends of everyone tagged): This setting allows you to post to your friends on Facebook. If others are tagged in a post, the audience is expanded to include the tagged person and their friends.
Custom , and uncheck the Friends of these tagged check box .
Only Me : This option allows you to post content to your timeline that is visible only to you. Posts with the Only Me audience will appear in your News Feed, but not in your friends’ feeds. When you tag someone in your content and select Only Me, the audience will not expand to include the person you tagged.
Specific Friends : When you choose Specific Friends, you can selectively share something with specific people or hide it from specific people. You can also share with specific friend lists if you have them set up. Specific Friends also allows you to share with groups or networks you belong to.
Limit who can see a post you’re tagged in .
You can also review posts you’re tagged in before they appear on your profile using the Review posts you’re tagged in before the post appears on your profile? option in your profile and tagging settings.
Remember that posts you hide on your profile are visible to the audience they are shared with elsewhere on Facebook, such as in News Feed and in search.
Remove a tag from a post.
