The internet is an amazing place to connect with people. Through online games, social media, or fan communities, you can meet others who share your interests from all over the world. These online interactions can be fun and can lead to what feels like strong friendships.

However, it is crucial to remember that online identities are not always what they seem. Someone can easily create a fake profile with a false name and photos. These profiles may not be authentic. The people behind them might pretend to be your age or share your hobbies to gain your trust, but they could be anyone. This practice is often called 'catfishing'.

The dangers are real. In Vietnam, authorities frequently warn about scams where criminals build a relationship over weeks or months. After gaining trust, they invent an emergency and ask for money. It is essential to be cautious and skeptical of anyone who asks for financial help, no matter how close you feel to them. A true friend would not put you in such a position.

To protect yourself, follow some simple but vital rules. Never share personal information like your full name, address, school, or phone number. Be suspicious of anyone who avoids video calls or meeting in a safe, public place. Most importantly, understand that a fun gaming partner is an acquaintance, not necessarily a trusted friend. True friendship is built on real-world trust and experience.
