Captchas are a useful measure to do rate limiting to prevent DoS, spam, crawling and brute-force attacks.
Using services like recaptcha is a stupid idea because you enable tracking of your users. Also defeating a captcha many sites use is way more lucrative than a per-site specific one which can be changed immediately when too many bad requests are detected.
In a forum we use a much simpler method, simply wait half an hour or something more, before sending the confirmation email, if someone registers. This avoids spammers who all use a disposable temporary email for registration.
Works like a charm. Captchas currently are obsolete and re-captchas de Google only a method to colect data of the user (if he don’t use a blocker, like everyone do). Because of this, Google search other methods to do this, FLoC and similar. Demential.
