AML policies may be similar across different websites, which is not surprising, since international AML rules are the same. We can rephrase some texts, add or remove some rules, but the essence will remain the same, so it may look the same.
If you pay attention not only to the paragraph where the requirements for providing documents are indicated, you will see that the rest of the information is completely different and the rules for working with exchangers are different.
Really, the important thing is to make sure that you store information that will make you compliant with regulators in case they knock on your door. Or even better, to have no information at all, so that in case something bad happens you can have plausible deniability while simultaneously running the exchanger anonymously.
Also you should consider hiring a dedicated support agent for the forum.
