Did you report it on Bitcasino Ann thread? Since most of the time their forum representative is active. Might he can do something if this issue reach to his knowledge and also you can also send a message to @LFC_Bitcoin or @jeremypwr maybe they can do something to contact other Bitcasino representatives to help resolve this possible issue.
What exactly do you think the original casino can do against phishing sites?
The most they can do is report the site and write a warning. This will certainly not prevent the greedy who will try to get the free $50. Also, I am sure this is not the only one site like this.
a small tip for identifying phishing fraudsters: Every serious casino will always choose a slightly louder domain, and that is almost never a domain with a - sign.
nice catch!
now since we are talking about bitcasino phishing site, I'd like to add that I found another bitcasino website(URL below) which I think is also a phishing site(I am not entirely sure). if you visit the website you will be shown a clone of bitcasino.io but if you click the register button you will be redirected to another site called live.bitcasino.io where you can fill up the registration form which clearly is not what happens when you click "register" on bitcasino.io.
https://www.bitcasino.com/
Also, all subdomains like
something.bitcasino.io are under the control of bitcasino.io. Anyone from the outside (without access to the domain administration) cannot create such a subdomain. And the page can look different when it comes to affiliate promotions.
I would even say that bitcasino.com is legitimate because the affiliate link to the original site is used for login/sign-up. It's just a slightly different approach to collecting referrals than usual.
