I am currently using CleanTalk, it’s working very good for me, 100% zero spam.
but it only allow 14 days trial and after that, I will need to pay.

Does anybody know any free anti-spam plugins (for BBPress) that doesn’t have Captcha?

Thanks 🙂

Give Akismet a run, it’s all we use here on bbpress.org it catches most of the spam.
