Unspam by Squelch Design is the simplest WordPress anti-spam plugin you can find for reducing your comment spam problem. Once installed there’s nothing to configure, and nothing changes to your visitors: No captcha or silly games. Once installed the plugin will simply randomize the names of the fields in the comments form on your blog and reject comments that are sent to the standard WordPress field names, or where bots have blindly submitted data to the honeypot fields. What this means for spammers is that they have to do quite a lot more work to send spam to your website. It may also make sending spam to your website unreliable as changes to your theme may upset their spam submission tools. Or they may have to resort to using humans to send spam to your website (not much I can do about that I’m afraid) which will cost them more money. Currently implemented: Names of fields are randomized every night at 12:00, Submissions to the standard WordPress field names are automatically deleted, Honeypot fields added to comments form, WooCommerce support. Additional (planned) features: Contact Form 7 integration Statistical collection, Automated blocking of persistent IPs, Opt-in centralized collection of comment spam and statistics for additional research.
