  • If you block proxies and VPNs it will stop real users.
  • reCAPTCHA also stops real users, often blocks proxies and VPNs, and isn't very good at stopping bots.
  • You can try a custom CAPTCHA. It can be a simple question. For example, if your site is about LEGO, you can ask how many studs are on the most common type of brick (it's 8). Bots that generically search the internet for "contact us" forms won't get it. Bots developed for your site specifically can be programmed to enter 8, but... why would someone develop a bot for your site specifically?
  • You can also try hCaptcha.

  • You can try a custom CAPTCHA. It can be a simple question. For example, if your site is about LEGO, you can ask how many studs are on the most common type of rectangular brick (it's 8). It doesn't have to be something that requires specific knowledge - as long as it's different from most other sites, like "how many letters are in 'the pizza'?" bots that generically search the internet for "contact us" forms won't get it. Bots developed for your site specifically can be programmed to enter 8, but... why would someone develop a bot for your site specifically?
