How can it prevent Captcha resolver services such as 2Captcha?

Just wondering how can it do that?

Sorry, just seen this. 2captcha and other solving services are notoriously difficult to stop, which is why you can bypass most bot detection software on their website (Google (13s) / Cloudflare (15s) / DataDome (12s) / Arkose (28s) / Procaptcha (28s)). The other companies listed here are a LOT bigger than Prosopo.

We have had some luck detecting and blocking 2Captcha in the past:

And we plan on continuing to block them whenever possible. Enterprise users currently benefit from dynamically created Access Control rules which apply whenever suspicious behaviour is detected. We'll be rolling out a restricted free tier version of this at some point.

We also just released stricter controls over IPs matching through the process in our last release. If you want to ensure that the IP of the person on your site is the same as the one we recorded, you can pass it up in the verify call and we'll do some additional checks.

I hope this clears things up! Please let me know if you have any questions.
