There was a scam phishing website that was making the rounds on Facebook. Someone had paid for facebook sponsored posts that was offering deals on the new S9 miner.
https://www.coinbureau.com/news/antminer-scam-advertising-facebook-watch/To the untrained eye, the domain would have appeared to be that of the Bitmain shop. Unfortunately, the domain employed a homograph attack that replaced one of the letters with a suspicious domain.
Users who were tricked by the phishing site though that they were buying the miner, were in fact handing the scammer $2,700.
There have been so many of these scams recently and this one even had a SSL certificate. Always be careful when buying something with crypto, entering your private keys or exchange login details!
