Hi! I have the exact same Bing bot that Front Door taggs first as good and then as bad as you can see in this picture. How can this happen?

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you have enabled "Bot protection rule set" on your Azure Front Door WAF and a Bing bot is logged as both good bot and unknown bot in your WAF logs and you would like to know why this is happening.
I checked the Client IP and it is a verified Bingbot IP address.
Refer : https://www.bing.com/toolbox/verify-bingbot-verdictMalicious IP addresses are sourced from the Microsoft Threat Intelligence feed and updated every hour. And I have seen previous cases where Azure Front Door WAF blocks a request due to false positives from Microsoft threat intelligence data, if the IP was previously flagged as part of a botnet.
In your case, this bot is not getting blocked as a bad bot but is being logged as an "Unknown bot".
Unknown bots are classified via published user agents without additional validation. You can set custom actions to block, allow, log, or redirect for different types of bots.
Refer : https://learn.microsoft.com/en-us/azure/web-application-firewall/afds/afds-overview#bot-protection-rule-set
Could you setup a custom action to allow this bot and validate if this is still getting logged/blocked?If you still see this Bing bot logged as Unknown or getting blocked as bad bot, we may need to engage the backend team to get this fixed. Hence, if you have a support plan, I request you file a support ticket, else please do let us know, we will try and help you get a one-time free technical support.
Regards,
