By creating fake exchanges, scamming people is a known tactic of scammers. We have seen many fake websites before and now. It is actually that scammers use human greed. Where people see little profit, they jump there without any proper verification. They lost their money and realized that it was a scam website. I will try to discuss how these scam websites are promoted by scammers.
These websites often use Telegram to promote. If you are in the Telegram group of a major exchange, and are an active member on the group. So here is 90% chance you will get private message from scammer. Scammers will politely chat with you. He would say it as if you really believed he was in trouble. He will offer you a good amount of money, if you help him. This is a trap. He'll say you create an account on this exchange. I am transferring funds from my account. He will transfer some fake funds to your account. Whenever you go for withdraw, they will ask you to deposit 0.02 BTC for verification. If you asked the scammer about this deposit, he will tell you to deposit and verify, then I will give you more money if you success! If you deposit any fund will never get your money back.
Most fake exchanges use the template of CEX.io most of the time. This is one of their most used techniques. If you find a link to such a website, then it is 100% scam website (except CEX.io). I have already posted on Bitcointalk many time about such scam website.

Here is the story, I asked about my problem on my yobit account on the telegram group, then after I sent my message, someone have message me about my problem and he sent me a link, saying that I need to log in on that link so I can recover my account on my yobit, by the way, that is my problem. Once I opened the link and see the website, I research about it before I sign up my account, and based on my research there is no reviews that I can see on the website so I didn't tried signing up the website. After that I messaged him saying that "F*ck scammer" and then he don't send me message anymore, and by that I can say that he is scammer.
The thing here is you should have make some research about some website that you are going to try, be wise and don't trust anyone so easily.
