PHP V5+ only! This plugin deletes spam from the comments table of the database. It does so by checking it for matches against the characters or words you have blacklisted in Settings->Discussion. Also on the Settings->Discussion page is a setting for the maximum allowed links that a comment can contain. This plugin will delete comments that have too many links. Spam can also be deleted if it has a url in the author url field. This is handy if you don’t have a author url form field in your comment form, and bots are submitting without using your form. Finally, spam can be deleted if there are any non US-en keyboard characters in any comment row. I don’t expect any foreign language characters on my blog, and while I know this setting may be a little harsh, it’s a spammy world out there, and sometimes ya gotta do what ya gotta do.
This plugin adds a menu item in the Settings section of the admin area. Currently only three options are available:
1) The frequency to run the automated process of removing spam. Default is twice a day.
2) Whether or not to remove spam that has been submitted with the website field. Default is NO (unchecked).
3) Whether or not to remove spam that has non US-en keyboard characters. Default is NO (unchecked).
