Lot of SPAM, even though honeypot enabled

Hi,

recently I launched a new web, and almost instantly (after a week or so) I starterd to receive spam from contact form. The honeypot feature is enabled.

Could it be cache related (WP Rocket plugin used)?
I have Caldera on many other sites, with no spam detected, but this is the first one with WP Rocket.

The site itself is not new though (previous version was not on WP), and client reported that they received the same type of spam from the previous contact form.

Any advices or tips?
Could I check somehow, if and how the bot bypassed the honeypot?

Thanks
