These 5 easy steps can keep you safe on Facebook.
1. Set the Privacy settings on your profile to "Friends." By doing this, you will be able to have control who has access to your information and pictures. For certain pictures, you can also select certain friends that you do or do not want them to see.
2. Always monitor pictures that other people put of you and tag you on. You can see the tagged pictures of you by going to your profile, click on "Photos"- you should see "Photos of You" and the number of tagged pictures. Click on that, and look through the pictures. You should be able to un-tag any unappealing photos of you, but people still have the ability to see it. Don't hesitate for a second to "un-tag" yourself from pictures that you do not approve of. Simply click "Report/Remove Tag" under the "Options" on the bottom of the picture. Also if you think that the particular picture could put you in a compromising situation, consult whoever put it up and ask him or her to remove it immediately. If they are your so called pals they should comply with your request.
3. Avoid putting your phone number, mailing address, or your home address in your profile. People often use words such as pet's names or numbers as passwords, so it is not recommended to publish them on-line.
4. Change your password every so often. Don't make your password something obvious such as your birthday or mother's maiden name. Try to have at least one capital letter, one lowercase letter, two numbers, and a symbol. The longer and more complicated the password, the safer you are from getting your account hacked. Always remember to log out after you're finished with Facebook, especially on a shared computer.
5. Be careful who you friend. Don't friend anyone out of your state/country unless you know them pretty well. Only friend people you know. You can add mutual friends that you don't know if you want to, though not recommended. Only friend people that you at least know their favourite colour, sibling’s name, pet’s name or something like that. Make sure they are the correct person by looking through their pictures. If they are not familiar, then remove them as a friend by getting to your friend list. Block anyone that seems to threaten or harass you.
