@Bryan710 This must be especially frustrating for you as a new host, as those first few reviews are so crucial for launching your listing. Unfortunately, since customer service is now fully outsourced, the agents have to follow a rote protocol and aren't usually authorized to make independent, nuanced decisions. So when you reported a review that unequivocally violated the content policy, that protocol kicked in - the review was deleted, and the guest was sent an automated content-violation warning.
You'd think that there would be a way for a human to manually redact the problematic part of the review. After all, they use a bot to scan reviews and listings for anything that looks like a phone number or email address and censor it with "(Hidden by Airbnb)." But you'll find that the company puts far more trust and autonomy in its algorithms than in its workers and hosts. You weren't given any options at the outset because there actually weren't any; officially, reviews can't be modified after they're published, so once the agent identified a violation, they were required to delete the whole review.
One takeaway here is that it's best to avoid contacting customer service whenever possible, as they usually just make everything worse. But it's for the best that your address isn't visible on your listing, so this is most likely case-closed as far as Airbnb is concerned. If you're still in contact with the guests, you can still invite them to bypass Airbnb and book directly with you for their next stay. Airbnb has no ownership of your future transactions with them.
