Honestly. Just report them and move on. 
Tell everyone to always do their due diligence on verifying all profiles and make sure you profile has information such as website and people can verify.

I had someone copy one of my websites years ago and everyone told me to go after the website and try to get it shutdown or the domain hosting company. I did that and it was nothing but headaches, I wasted my time and energy.

Someone who was successful later told me never to waste your time & energy. In fact, the fact he was copying your website meant you were doing something good that someone went out of there way to copy my website.

He later told just inform your website users to keep safe and make sure they are logging into the right website but most importantly keep an eye on the website to see if he adds new features and things that could compete against your website.

Use your time and energy and improve your website and not go after impersonators. They all end up losing in the end and he also told me something I will never forget.

Impersonators bring taffic to your website. Free traffic. It's free advertising.
