Forms spam bot prevention

Is there any build in logic to prevent bots from sending unlimited form submissions? I’m not talking about options to integrate captchas or something else. Just want to know if webflow did something so that I can ease the receiver of the form.

We have rate limits in place to prevent multiple sends that match a certain type of signature. We will also not bill you for any spam submissions that we detect, or that you report.

Hi Bryant,

The same spammer keeps messaging us a few times a week despite reCAPTCHA being activated.

Any way we can prevent that from happening? Maybe excluding submissions from that domain address?
