It would be good for newbies and many people on this forum that are not even newbies to read the terms of service of the gambling site that they are using. Having more than one account is against the ToS of all or most of the gambling sites.
The terms of service of any platform is probably the most ignored page; many just scroll it to see how long the pages are and just hit agree, you can do that on other platforms I have a friend who ignores a lot of terms because they looked and are all the same, but unfortunately its different when it comes to gambling platforms.
Casinos differ from one another when it comes to their terms, so it's your responsibility to check the terms read it take your time and, as much as possible, understand it, And when there's a new update, do the same, its important if you're a regular gambler to make it a habit to check the terms because money is involved here, and understanding these terms will save you a lot of headaches in the future.
