One of the first things you can do to recognise a rogue operator is to open its website and scroll to the bottom of the homepage. Here, you should see the regulation and licencing information, complete with the operating licence number. If this info is missing, you are most likely dealing with a rogue casino. However, the most surefire way to know whether a casino is rogue is to read player reviews or look at the list of rogue casinos on the Casinosters website.
