Quick verdict on Akismet Anti-Spam
Akismet ships with WordPress by default and remains the most-effective anti-spam plugin for the platform. The product is conceptually simple: every comment or form submission is checked against a global database of known spam signatures, built from billions of submissions across millions of WordPress sites. Spam is silently discarded (or moved to the spam queue, your choice) and legitimate comments pass through. For personal blogs, Akismet is free. For commercial sites — any site with ads, products, or services — Automattic requires the paid tier ($10-$50/month depending on traffic). This catches many small-business sites off guard who assume Akismet is permanently free. For sites that want a fully free anti-spam alternative, Antispam Bee is a reasonable substitute, though without Akismet's global database it catches less.
