This sounds like a very nice initiative, regardless of who might be behind it.
I hope that "whitelist" is also largely based on "hand made" content as there seem to be those who create large amounts of seemingly good content using so-called "text spinners" (AI) to make it look original. Not saying it's happening here on Blurt, but I do see it around blogging sites.
It's definitely happening here on Blurt. That's the reason for switching to a whitelist model. At least this way, the humans who add accounts to the whitelist can do some checks before adding someone. The way it was before, the bot did some checks, but the scammers would eventually figure a way to bypass those checks since they aren't that difficult to figure out. It's much better now even though the humans can also be tricked.
There are tools that can be used in order to determine if something was generated by AI. I came across this one today: https://gptzero.me/
