December 14, 20225 min read

How to be Social Media Savvy

It is possible to take part in social media and still maintain a semblance of privacy. To accomplish that, keep some of the following things in mind when posting on social media platforms such as Facebook.

Do not write in a fury

If you are angry, inebriated, or simply have a big secret you are itching to share, that is the time to step away from the keyboard. What you think is hysterical or outlandish now might only serve to embarrass you later.

Do not ignore the privacy controls

Every application and online service offers customization for your profile. Use it. For example, on Facebook, limit your account access by setting who can view your posts to Friends, Friends of Friends, or Only Me. Do not enter contact information, such as your phone number and residential address. Restrict access to your photos, birth date, religious views, and family information, among other things. Give only certain people, or groups of people, access to these items, or block specific people from seeing them.

Do not post your child’s name in a photo caption

Do not use your child’s name in photo tags or captions. If someone else does, delete the name’s tag by clicking on the Remove Tag option. If your child is not on social media and someone includes his or her name in a caption, ask that person to remove the name. Do not share online the details of your child’s life. Your child’s sports practice, such as soccer, is likely on a regular schedule, which a predator reading Facebook profiles can be easily track.

Do not mention when you’ll be away from home

When you tell your Friends through social media that you are not going to be home, you are inviting criminals who are trolling Facebook profiles—especially unsecured profiles—to your then-unoccupied house. Keep in mind it takes only a few minutes to rob your home or harm your family. Even a mention of a quick run to the store is unwise.

Do not use a weak password

Avoid using simple names or words that can be found in a dictionary as a password. Even with numerals tacked on the end of the word, these are not secure passwords. Instead, use a knuckle-breaker password—one that requires upper and lower-case letters, in combination with numerals and symbols. A secure password should have a minimum of eight characters.

Do not put your birthday in your profile

Your birth date is an ideal target for identity thieves, who could then use the date to obtain more information about you, potentially gaining access to your bank or credit card accounts. Do not put any personally identifiable information about yourself in your social media profile accounts.

Do not let search engines find you

To help prevent strangers from accessing your Facebook page, go to the Search section of Facebook’s privacy controls and select “Only Friends” for Facebook search results. Be sure the box for public search results is not checked.

Do not ignore privacy settings updates

The Terms of Service for apps and social media services changes constantly. Keep up with any notices that changes have been made to the security and third-party access permissions.

Control your child’s social media activity

Most young people are now using social media platforms other than Facebook, including Instagram, Twitter, Snapchat, and TikTok. Get in the habit of having your child part with his or her smart phone each night so the phone can spend the evening recharging its battery—an excellent opportunity for the parents to then peruse the contents of their child’s social media profiles. Sign up for a monitoring app such as Bark, Safer Kid, or Web Watcher to monitor your children’s social media activity on their phones.

Do not Friend your employer

Sure, it might seem like a great idea to Friend your boss—that is, until you decide to rant about how much you hate working overtime or you post photos of your day at the beach the same day you called sick into work.
