basically what the title says

the ones i’m aware of:

  • google’s recaptcha
  • cloudflare’s hcaptcha

cloudflare being better for privacy compared to google, but still not great afaik

    Captchas are obsolete novadays, current AI and even bots solve them better than any human. To avoid spam they are useless more and more, better as done by some forums, they simply wait 30-45 minutes before sending the activation mail, no spambot with an 15 minute mail will recieve it. Another one is the honeypot system to block bots.
