Add-on · XenForo 2.3
SpamGuard
Hybrid spam protection for XenForo, GDPR-focused
In development1.0.0 AlphaNot released yet
Classic rules check first and cost nothing. Only borderline cases go to an AI provider of your choice, pseudonymised beforehand. The add-on runs entirely on your server.
Hybrid instead of everything to the AI
Honeypot, time trap, StopForumSpam, link limits and further rules add points. Only content between the thresholds is checked by the AI. That keeps API costs low.
GDPR as a core feature
Usernames, email addresses, IPs and URL paths are replaced before every AI request. EU providers can be selected and are labelled. The audit log stores no content and has a retention period.
No SaaS in between
No infrastructure of mine, no data through my servers. You use your own API key (BYOK). Errors never lead to unchecked publishing: when in doubt, content is moderated.

Principles
- Failures never block the forum. If the AI does not respond, content goes to the moderation queue. If StopForumSpam is down, the other rules keep checking.
- No content and no prompt in the log, only score, rules and decision.
- Integrates through the built-in XenForo spam checkers, without changes to controllers.
Requirements
- XenForo 2.3
- PHP 8.1 or newer
- For the AI review (Pro): your own API key, e.g. Mistral
Status
Invision Community 5 will follow after the XenForo release.
