How to cancel all comments in a while

[sko33]

Because I'm cancellin 100 for for a time but are a lot of spam comments.
Then I'll like to know if there's a utility for cancell all comments in a while.

Delete the comments. Then start using the captcha plugin to prevent automated spam comments being placed and disable the option for anonymous comments. That way somebody would have to register before being allowed to comment.
