Nice, but captchas are never a good measure to avoid bots, only to annoying users, apart from spying them, if it is from Google. Long before AI, bots could solve captchas better than humans. It is a clearly obsolete method. Apart the system used by Proton is impossible for blind users, Google captcha at least had an auditive captcha too.
This is the problem. I remember a very simple method to avoid spambots on a forum with great success. It is based on the following idea: A spambot or even a spammer necessarily uses a disposable email to register. These emails are usually not valid for more than 10-30 minutes, just to be able to receive the confirmation link. In this forum, the sending of the confirmation email has been delayed for half an hour due to this and with this the spam problems have ended. A normal user, if they really want to sign up, waits this time without problems. Then the usual 50 messages before being able to put a link as an additional measure. Simple and without third party apps.
