Manual Install Instructions for SMF


Prevent spambots from registering on your forum. The SMF BotBuster uses the API to check each attempted registration against the database of known bots. Both the email and IP address are tested against over 2 million  bot signatures (with more being added every day).

Failed registration attempts are halted with a false "Registration Disabled" error message. Additional "failure" actions are easy to add (such as forwarding the bot to, displaying mysterious, random error messages, or returning a frustrating "CAPTCHA Failed" error).

  • Works with SMF versions 1.1.x and 2.x (including 2.0)
  • Minimal code changes, no extensive modifications required
  • Will not conflict with other mods - adds only a single line of code
  • Checks both email and IP to ensure a high detection rate
  • Provides results in simple string format or XML format
