When someone mentions you in a comment on Facebook, there are a few factors that determine who can see it. Firstly, only you will receive a notification when someone mentions you in a comment. This notification will appear in your notifications tab, alerting you that someone has mentioned you in a comment on a post.
However, the visibility of the mention itself depends on the privacy settings of the post and the actions taken by the person who mentioned you. If the post is set to Public, then anyone who can see the post will also be able to see that you have been mentioned in a comment.
If the post is set to a more restricted audience, such as Friends or a specific group, then only those who have access to the post will be able to see the mention. However, it’s important to note that if the person who mentioned you later deletes their comment, the mention will also be removed and no longer visible to anyone.
