That is completely suspect to require a full name and address. A reader doesn't need that information unless they're going to google you prior to a "reading".
Any updates? I just took a look at her website and you have to provide a lot of personal details like full name and full address (not payment-related). She is also rather expensive (for me) so I'm hoping to hear more feedback before I make the decision 
She's not a scammer. I've been reading with her since 2013. She's very far from a scammer. She's only recently had that requirement for multiple reasons. There's so much AI, bots, scammers out there so she's requiring basically proof of actual human, no scammers from random places etc. It's like when you purchase a reading through paypal it lists your payment method, full name, and address on the receipt anyway. Nevertheless, I can attest to her NOT being a scammer and not "screening" to Google before readings.
