After my initial configuration of the phpBB, I noticed a few new members which seemed great. Then I realized it was spam. So, I started doing some research into spam prevention.
I found a link on the phpBB support forums on preventing spam in phpBB. I was already using the Newly Registered User Group but I had approved the members. I decided to try the Q&A CAPTCHA. I made a simple astronomy question for the Clear Sky Tonight forums.
But, the downloadable CAPTCHA plugin sounded like a better solution on the idea that the more unique your forum is, the harder it will be for the spambots. I looked at the plugins that were available and selected the Sortables CAPTCHA plugin. I checked a sortable list of the different planets.
As an extra measure, I configured a Custom Profile Field.
With these two measures in place, I haven’t received any spambots.
