Our analysis
AI-assistedAnti-Captcha is a WordPress plugin designed to block spam by preventing automated bot attacks on specific actions such as posting comments, registering for new accounts, and requesting lost passwords. It uses a nonce key that is inserted via obfuscated JavaScript to ensure that only legitimate users can perform these actions.
This plugin is suitable for WordPress site owners looking for a solution to reduce spam without requiring users to interact with captchas. It marks comments without a valid token as spam, allowing for manual approval later if needed.

From the developer
filiw's own description of Anti-Captcha, lightly tidied.
Anti-Captcha is a transparent spam solution that does not require any end-user interaction.
It is based on a nonce key, which is dynamically inserted using randomly generated (and obfuscated) javascript.
The aim of this plugin is to prevent automated attacks (by bots) on the following WordPress actions:
- Posting comments
- Registering for a new account
- Requesting a lost password
When a comment is posted without a valid Anti-Captcha token, it shall be instantly marked as spam. This way, you can always manually approve this comment in hindsight if it appeared to be sincere.
