Ah gotcha. Yep I understand that level of concern or security on their side. There's lots of fraud perpetrated by new cloud computing accounts. I wonder if an impossible to solve puzzle is intentional. As in, have they modeled human behavior to know what a human would do next that bot wouldn't. If it helps, some cloud providers are even more stringent. If you ever try to open an OCI account you might have to wait a week or more for a human operator to approve before you can get into your account. Some have waited upwards of a month.
