Sometimes if a casino has multiple brands you do not always need to verify each account. They can in some instances link those accounts together.
But also in some countries there is ways that they can verify someone without requesting documents. UK as an example. They can check the electoral roll and also do a soft search credit check to make sure your details match etc etc.
Sky Bet/Vegas do this and others do too.
Then there is those casinos who do not do those checks who just have a X withdraw threshold and once that player reaches that threshold it triggers them to then ask for the documents. that threshold is usually only about 1.5K. So if you did that all in 1 go in your first withdraw then it is likely you will be asked for documents.
Thresholds can vary too. Then there is those casinos that have over the top verification processes. They allow players to deposit and deposit and deposit yet as soon as they come to win or withdraw they bombard them with asking for documents and in some cases like Guts. They keep sending the requests over and over again even if you keep sending and keep getting verified. I got asked by guts basically once a week and every single time they got verified, then next week again they asked again for the exact same documents. Some casinos are just bad when it comes to verifying. Then there is delay tactics too, those casinos that use verification times to delay withdraws for as long as then can do.
