Custom PHPBB3 Anti-Spam Mod Addon

**Overview**: I need a custom PHPBB3 Mod that will eliminate spam registrations on PHPBB3 message boards. This should not only eliminate spam registrations, but spam postings as well. It should include things like random questions (What is 4+5?) during registration... and a question must appear every time between the first 5 posts (but not after) This will help to combat spammers. I also want random questions to appear when the user is registering for an account.... two questions for each registration. They both must be correct in order for the account to become activated. **Backend**: I'd like a very simple backend for the board administrator to be able to change the questions that will be randomly displayed. This can be a PHP based script that uses the same MYSQL database that holds the random questions. The admin should be able to create as many questions as he/she wants (thus making it harder for spam bots to attack the board). ## Deliverables Overview: I need a custom PHPBB3 Mod that will eliminate spam registrations on PHPBB3 message boards. This should not only eliminate spam registrations, but spam postings as well. It should include things like random questions (What is 4+5?) during registration... and at random post intervals... for example: If a new user, they will post once... and before their post is approved... a screen will appear asking a random question they will have to answer before the post goes up. Same with second post, third, fourth, and fifth. After the fifth post... they may not get a question until their 25th post. And after that, their 100th post, and after that they will not be asked again. This will help to combat spammers. I also want random questions to appear when the user is registering for an account.... two questions for each registration. They both must be correct in order for the account to become activated. Backend: I'd like a very simple backend for the board administrator to be able to change the questions that will be randomly displayed. The admin should be able to create as many questions as he/she wants (thus making it harder for spam bots to attack the board). Must come with a page that will automatically create and install tables on the user's database. Testing: This must be tested very well. Instructions must be written for others to install this plugin onto their site. This will not be a plugin exclusively for me, but for other people on the internet who run PHPBB3 message boards...
