I am looking for some suggestions and help on how to make sure that my Xenforo is as secure as possible, and also very good with fighting off spam bots. Lately my forums has been getting a ton of spam bots coming through. The past 5 days, every day there has been 1-2 spam bots posting on our forums. So what can I do to stop them? What can I add, and what are the best settings I can set on the User Registration settings? Thank you!
