I'm guessing it's a modification of a scam that's been around podcasts and even (sometimes fake) conferences. Invite someone, then "oh hey you need to pay X for Y" or maybe asking for some donation to support. Now they're just automated attempts to grab cash
Have you read Hanna Reichel? I have not read this book, but I've listened to some interviews they've done and am currently reading their devotional book. This is more theology focused: https://www.wjkbooks.com/bookproduct/0664268196-after-method/
Not sure of your religious background, but I'm an ex-evangelical and, while I'm a white, straight, middle-aged guy, I've found nothing has helped me more than reading non-white and/or non-cis folks in recent years. Mainly because it's perspectives that I have not only appreciated before, but actively thought of as bad in the past.
