You’re right that it was a bit of an oversight on my behalf, as the links were only generated after a verified human user action (signup) I had assumed the 1 time links to their email would be safe. But regardless of the link action, it shouldn’t be passing that data to Bingbot to crawl and (possibly) index in search engine results. Private email data should not be shared with search engine crawlers IMO.
