I notice there are none of those annoying google captcha quizzes or math tests at the bottom of your new topic forms. I know you must be using something to protect from spambots. Any chance you can share what it is?
Sure. We tried a whole lot of different solutions. But all of them slowed down the speed of our site and were very non user friendly for the members of our community. After searching extensively for a better solution we found CleanTalk. Their spam protection runs in the cloud so it does not affect the speed of our site. It works in the background so no need for those tests and quizzes. It also protects not only our forums but also our member login forms and contact forms. Been with them now for a couple of months and all good so far.
Their website is located here if you want to check it out:
