There are several ways to control spam on a WordPress site:
1. Use a spam blocker plugin: There are several popular and effective anti-spam plugins available for WordPress that use different techniques such as blacklist/whitelist, captchas, and AI to prevent spam comments and form submissions.
1. Enable comment moderation: This feature allows you to manually approve comments before they appear on your site, preventing spam from being published.
1. Add a robot.txt file: This file can help prevent spam bots from crawling your site and submitting spam comments.
1. Use reCAPTCHA: This free feature provides a more user-friendly alternative to traditional captchas, allowing legitimate users to submit comments and forms while preventing spam bots from doing so.
1. Limit login attempts: Some plugins allow you to limit the number of login attempts, preventing spam bots or brute-force attacks from accessing your site.
In technical terms, these methods work by using various algorithms and techniques to analyze user behavior and distinguish between legitimate and spam submissions. This may involve using machine learning models, IP address blacklisting, user agent analysis, or other methods to identify and prevent spam submissions. Some plugins may also use APIs or cloud-based services to validate submissions in real-time and reduce false positives. Overall, the goal is to make it harder for spammers to bypass website defenses and maximize the effectiveness of anti-spam measures.
