1. Inappropriate Photos and Explicit Images
You may unintentionally or deliberately share sensitive images, but it’s best to avoid posting explicit photos to prevent potential trouble in the future. Some individuals may threaten to distribute explicit images online to coerce victims into following their demands. Moreover, in Vietnam, sharing such images can lead to harsh judgments from others due to strict social views.
Facebook serves as an easy platform to connect with the community, but users should be aware that many recruiters may visit personal profiles to determine if a candidate is suitable for a position. A profile filled with party photos may not reflect well in a professional context. While most people don't mind a picture holding a drink and pretending to sip, things can take a negative turn if it’s an image of someone visibly intoxicated. This type of photo can be off-putting and gives an impression of unprofessionalism.


2. Complaining or Badmouthing Friends
Never complain about how much you hate your job, or speak ill of your boss or colleagues. If you do, there's a high chance you might be fired, but even worse, no one will want to hire someone like you in the future.
Facebook is a platform where you can share both your joys and sorrows with your friends, but don’t turn it into a trash bin for every frustration you feel. Complaining about an unpleasant boss, or criticizing an unattractive classmate… these are things you should never broadcast on Facebook. They might even be on your friend list and feel hurt by your posts. It's always better to keep things discreet.


3. Confessions
There have been cases around the world where the police have caught criminals thanks to their confessions posted on Facebook. Of course, we don’t encourage you to avoid taking responsibility for wrongdoings, but it's better to confess to the authorities rather than broadcasting it on social media. Just imagine, if someone were to confess to a murder on Facebook, even before law enforcement could act, they might already be facing retribution from the victim's family.
Tax fraud? Annoyed with your boss? These are things you should never post on Facebook. While Facebook's privacy settings allow you to create specific groups to share certain information, once sensitive or illegal content is shared, it becomes incredibly difficult to remove or prevent it from spreading. There are many examples of people getting fired or even arrested due to oversharing on Facebook.


4. Your Mother's Real Name
"Your mother's real name is highly sensitive information, especially since it's frequently used as a security question for various websites," quoted from The New York Times. Credit card companies, your wireless service provider, and many other companies often rely on this valuable piece of information to protect your personal data.
Do not expose this information, as some banks and telecommunication companies use your mother's name to verify your accounts. If someone with ill intentions knows your mother's real name and uses it to impersonate you, they could gain access to your personal account with serious consequences. Just use a nickname instead!


5. Home Address
Sharing your home address makes it easy for anyone, including ex-partners and people you've worked with, to know where you live. This could lead to unwanted consequences. For instance, some burglars have been known to use Facebook to identify targets when users disclose that they’ve left their home.
It’s not an issue if you only want friends to know where you live, but it becomes a bigger problem if unwelcome visitors use the information to break into your home with ill intentions. Imagine you’ve just ended a relationship and moved to a new house, but you unintentionally post your new address on social media. Your ex could easily find out and show up uninvited.


6. Your Asset Information
It’s reckless to disclose your asset information. As you may know, greedy thieves are always looking for targets, and if they believe you have wealth, you might end up on their radar. This is very dangerous! Avoid posting photos of bank statements, valuable possessions, or your personal items on Facebook, as it may not only appear as flaunting but also puts you in harm’s way.
Users have become more cautious about personal data leakage, but sometimes this risk is overlooked or accidentally ignored. Especially when shopping through Facebook, be sure to remove any bank card details; otherwise, this information may be stored online and stolen by hackers.


7. Information About Your Children
Never disclose specific details about your children on Facebook. They could become targets for kidnappers or face psychological threats. In fact, many celebrities are cautious about revealing their children's personal information to protect them. When taking family photos, avoid tagging your children’s names. Additionally, avoid introducing family members in too much detail on your profile. Remember to think carefully before sharing anything on social media.
Always think twice before posting pictures of your children online. Your children are too young to consent to having their images shared publicly. Also, if these photos fall into the wrong hands, they could be at risk. It’s best to avoid posting photos of your children on the Internet to minimize any potential risks. Similarly, be cautious when sharing information about where your children go to school or play. Simple details like these can be used by malicious individuals to track and harm your children.


8. Updating Your Current Location
Social media users can put themselves in danger by constantly updating their location on Facebook. Set aside any personal opinions and truly consider the real threats of sharing too much about your whereabouts, such as vacation spots or where you are at any given moment. Aside from inconveniencing your friends online, consider the risks of inadvertently inviting burglars into your home.
Many young people have a habit of checking in at fun locations, which means sharing your current location on Facebook. This is especially dangerous if you are a public figure and could be a target for kidnappers. These individuals can track your whereabouts and execute their malicious plans. A recent example of this was the incident involving Kim Kardashian. Her habit of checking in at every location she visited made it easy for criminals to track her down and kidnap her for ransom.


9. Publicly Sharing Your Long-Distance Travel Plans
Remember, it's not a good idea to share your long-distance travel plans to avoid unwanted risks. A consultant in New York advises that by publicly announcing your upcoming travel, you are giving burglars the perfect opportunity to break into your home and steal valuable possessions. Therefore, if you have a lot of assets, avoid sharing too much about your travel plans. Publicly posting about your trips can expose you to several risks.
According to This is Money, many travelers have been robbed after posting their vacation plans online. These individuals also risk having their insurance claims denied. While it may be fun to let people know you're visiting a beautiful island or exploring a new destination, sharing your location is very dangerous. Criminals could take advantage of this information to know that your house is empty and steal your belongings. Experts advise limiting your 'check-ins', setting your location to friends only, and never sharing your whereabouts during important work, overseas trips, or when dropping your kids off at school.


10. Personal Phone Number
On Facebook, you have the option to update personal information such as your name, date of birth, address, and phone number. However, there is no need to share your personal phone number unless you want to become a target for financial, insurance, or beauty companies, who will bombard you with sales calls. If you use Facebook for business purposes, it's better to provide a dedicated phone number for customer contact.
In everyday life, you may have received calls from loan companies or real estate agencies, even though you've never provided them with your phone number. Most likely, they obtained your phone number from Facebook. When signing up for Facebook, users are required to provide a phone number, but you can choose to use a secondary number or hide it to avoid being exploited. According to some security experts, scammers can easily discover your address and other private information with just your phone number and specialized tools.
