Add captcha to faucet
To further protect ourselves from sybil attacks we're adding a captcha to the faucet frontend flow!
Checked the mixpanel usage numbers and it does not look like adding the captcha has decreased the amount of faucet usage: https://mixpanel.com/project/3232303/view/3741795/app/boards#id=7873539. It is possible that the captcha is not properly filtering out bots since it seems like we still have a suspicious amount of claims coming through.
I just tried it and was not presented with a captcha -- perhaps this is not working?
@jvmi7 has more context on this, but Privy uses a Cloudflare turnstile captcha that they intentionally hide in the UI and it will only be shown if the captcha fails
ohhh cool so its just something we enable through Privy? got it, thanks for explaining!
the privy captcha has not been effective at stopping bots, we may want to consider adding our own captcha within the claim flow
