Once a domain is on the Bing station group, basically, by doing wildcard domains, you can keep the spiders in captivity.

Directly check on CN Bing whether your keywords are blocked or if the site is blocked. If blocked, you can directly block bingbot.
Otherwise, bingbot will still consume server resources. Other malicious bots: https://k7blog.com/22.html
