They have their own internal security team, that handles activation on a case by case basis. Some users need to verify at the beginning, some after a week and other do not have to verify at all.
As you can imagine, at that price point, people will abuse the sh* out of the platform. From public posts it lookalike the main indicators are: - country you provided - IP based Country - Payment method - Payment method returned country - order size - order pattern (something like spawn a server, abuse stuff, order new OR many servers at the beginning)
Sadly you just need to wait. I wish they would have other solutions. But for now that’s it :-/
