I've been observing that the custom captcha process itself is a very good bot repellent because someone has to reverse engineer captcha behavior and most malicious actors actually don't know how to. Sprinkle a bit of obfuscation and your 2+2 captcha will be more effective than pages of traffic light selections.

The captcha was a 'select the right picture (singular)' type, and didn't have a nonce so I just attempted every single answer and would eventually get in. I was able to build up a database of correct answers before they fixed that.
