Also to spark a conversation whilst we are here, most captcha providers support a call back function so we can remove the useless submit and automatically pass if the user succeeds can help reduce one click.

Pros:

• less for user to do
• less churn
• works with turnstile managed mode (automatic successful)
• helps me stop changing color of submit button 🙄

Cons:

• could be more prone to allowing bots that solve captcha (Even though detecting the form is quite simple)

Can this be added to the HAProxy bouncer too?

Yes, we should really just integrate the plugins at build time instead of copy pasting them. 🤔

Just need a proper documentation on how we can switch between providers. Otherwise lgtm 👍
