Seeking a reliable captcha to stop forum bots

[Galileo]

A bunch of bots have appeared on the forum, massively registering accounts and posting spam. Moderation can’t keep up, and the user database is becoming cluttered with fake profiles. I want to add protection against automated registrations on the account creation form. Which captcha would you recommend? It’s important that real users can pass it easily, while reliably blocking bots.

Bot spam is a real headache for forum admins, and you definitely need something stronger than basic captcha puzzles that bots can easily solve nowadays. The key is finding a balance between security and user experience - you want something that stops automated registrations without frustrating legitimate users. Modern bot protection goes beyond simple image recognition and uses behavioral analysis, device fingerprinting, and risk scoring.
