If you’re having spam problems on your forum, we also recommend enabling the Stop Forum Spam addon. This is a free third-party service that compares IP addresses and email addresses against a list of known spammers. You can adjust its sensitivity in its settings page. Contact support for help tweaking those values, or if you still get high levels of spam after enabling both those addons.

We really hate spam at Vanilla, and we’re constantly working to improve the tools in our arsenal to make sure as little as possible ends up on our clients’ forums.
