Take YouTube, for example. It is a social media where you can share clips of funny videos. But it might not be what you think. Most people in their profile pictures put there face inside. But some hackers on YouTube don't put their faces so you don't know who they are. The next thing they do is make a video on a free give away including phones,free game currency and money. On most give aways, you have to put your personal information in order to receive the prize. This is called a con. When the hackers receive the information they use it to hack into your account leaving you helpless as you cannot take it back. What you should do in this situation, is make sure you know this person who is making the giveaway. For example as your family or friend or just someone you trust. CURRENCY GAMES Various popular games such as clash of clans, war robots and boom beach all have the option of buying game currency. Once you have bought any amount of game currency, the people who have made that game will instantly receive a message that you have spent money on their game. The next thing they do is make you carry on playing their game. And when you are off your device for a week or so,the next time you go on it they will give you free game currency because they want you to carry on playing their game.
