Scammers are always ready to clone or develop anything that they think will make them money, so if your business is pulling heavy traffic and has lots of users, just be ready for impersonators. We just have to be careful, because no matter how perfect the clone looks, there will always be an open spot to differentiate the fake from the original when we look down closely.
The only option is to report these website to Google.
Even when we report most of this sites google won't just stop bringing them out when we search, because most of them are not on the top 10 search because they are frequently used or search but because they paid google for that ads space.. google most of the times usually don't care what they feed to the public providing that the companies which they advertise are paying them huge. It's just business for them.
