What moderation option allows for control over comments in Blogger?

The option to require "word verification" before posting is a moderation feature designed to help control the types of comments that appear on a Blogger site. This feature adds an additional layer of security and helps prevent spam and unwanted comments by asking users to complete a verification step—usually by typing in a displayed word or phrase—before they can submit their comment. This ensures that only legitimate comments, from users who can complete the verification, are allowed on the blog, thus fostering a more positive and relevant engagement.

Other moderation options exist, such as disabling comments entirely or allowing comments without any verification, but these do not provide the same level of control and protection against spam. Automatically deleting spam comments can be helpful, but it does not prevent unwanted comments from being posted in the first place. Requiring word verification strikes a balance between encouraging interaction and maintaining control over the content that appears on the blog.
