OOPSpam
6,000+ active installs · Rated 4.9/5 · Updated October 23, 2026
A plugin connecting WordPress forms and comments to the oopspam filtering service, which checks submissions in the background instead of using captchas. It can filter by country and language, block VPNs, apply rate limits, keep logs on your own site and protect WooCommerce checkouts. It suits busy sites with spam from both bots and people. The plugin needs an oopspam API key; a free plan includes limited monthly checks, and paid plans add more.
Pros
- Background spam checks with no captcha
- Works with WooCommerce and many form plugins
- Spam and ham logs kept on the site
Cons
- Needs an oopspam API key and a plan once the free calls run out
- Each submission is sent to the oopspam API
- IP location lookups use a third-party geolocation service
