Want to add you as a friend of Fetion? Is it a message from a liar?

These can be divided into two situations. One is a real classmate or friend.

The second is a lie. Features: you don't know him, your real name is not reported in the other party's information, or what column group it is, or you won the prize. When you add them, they will send you some winning information to cheat you. For example, if you reply, you will deduct a lot of prepaid phone bills and so on.
