Hello! I have a XenForo forum for my server (www.happy-hg.com/forum/), but lately it has been spammed by loads of spam bots DAILY! Every day non-stop, I would find in a random forum, threads of Bots advertising stuff and doing the normal bot behavior (The bot registers, posts thread(s) advertising something and then never ever log-ins back again) Furthermore, I've tried ALL THE POSSIBLE CAPTCHA WAYS to prevent these annoying pests from registering at my forums (http://gyazo.com/b2c1a1981974fbacb3d7f43c4fe63f25), but they keep doing it My Question was, how can I reduce/remove the amount of bots that register at my forum and spam it everyday? Is there a XenForo plugin or a special captcha configuration that stops them? Please Help! Thanks!
