Privacy checks related to How to Block Someone on Facebook

Privacy settings work best when you review them as a group. One setting may hide posts, while another still exposes your profile details, friend list, tags, or search visibility.

  • Review who can see future posts and older public posts.
  • Check profile details such as work, school, relationship, phone, and email visibility.
  • Turn on tag review if you want more control over posts connected to your profile.
  • Review connected apps and websites periodically.

Practical privacy habit

After changing a privacy setting, view your profile from another account or use Facebook's available preview controls if shown. This is often the fastest way to catch details you forgot to hide.

  • Check public-facing profile details.
  • Look for old public posts that still reveal personal context.
  • Avoid posting addresses, travel plans, documents, or recovery information.
  • Repeat the review after major Facebook interface changes.
