I used the form on the author of the book's website a few weeks ago to invite her on our books podcast:

She didn't respond, which is fair enough, it's probably not big enough to be interesting to her. But then I got auto-added to her PR mailing list. I didn't ask or consent to be on the PR mailing list (all the page says as of now is "To contact Sarah, please complete the form below"). Seems I was just added because I used the "contact" form.

Auto-adding someone who contacts you to a PR mailing list is a dark pattern. Seems she learned something at Facebook. I found it ironic.
