Are you sure that they are pretending to be Roobet casino? I am asking because their website looks completely different from theirs, and it doesn't make much sense to pretend to be something else if you don't copy the look too.
When i tried to open that link, it only show me a registration link (i haven't tried to click that)
Weird, when I clicked on that link, I didn't get any registration link, nor could I find one one their website.
