The bots would just slow down then. Their time is ~free.

reCAPTCHA is one of the better captcha because they do a decent amount of browser fingerprinting and their captcha are interactive.

Still there are services for solving them. Fun thing is you only need to pay those services for first ~50K captcha and then you can train your own solver using the data you collected.

Ultimately, captchas only serve to increase the cost of running bots. If what ever your trying to protect is worth more you will fail.

I have a suspicion that truly effective browser fingerprinting breaks GDPR along with other privacy laws.

only if you can tie together the fingerprint and the identity.
