They aren't giving useful information, they are posting an opinion insinuating that people who use """""fake""""" (ie. non-personally-identifying) e-mail addresses are fraudsters.

They did not provide any meaningful insight into the field, they are simply insisting that e-mail addresses should be a tool for personal identification because it saves them money over doing real KYC. In other words, they believe KYC should be slanted further in favor of corporations and against customers, such that KYC is publicly available for free, because they value not doing the work of verification over humans having any privacy whatsoever.

As they are entitled to post their opinion on humans having no privacy rights, I am entitled to post mine and point out the hypocrisy of them choosing to participate in this forum privately while advocating for and boasting about denying service to other people who attempt to protect their privacy.
