My site was is attacked by spam through ContactUS form and subscribtion form

Hi,
My site was is attacked by spam through ContactUS form and subscribtion form even if I have enabled google captha V3 they have managed to bypass it. And now I am getting 10 emails a minute from product questions even after I disabled them even if I had set the captha the way that I even wast able to send the message.
Could someone help me? I am willing to pay to someone who will sort this problem out, because my page emails are now not working and customers cant get confirmations of the orders etc.

printscreens of the problem attacker if from honkkong and sometimes he doent even have IP so IP block might not work + he is changing IP all the time
I am lokking for someone who can solve this

What version of nopCommerce ?
In my experience later versions are much less susceptible to hacks

Hi, it is 4.50.2 I didnt see the point upgrading to .3
Luckily i have blocked two IP the attacks were coming from and it stopped for now, but if they can bypass the google captha this might not by the solution long term

How can I add an extra field from the contact us page? We are having the same problem 4.404 version with capcha v3 enabled

did you mean,  that you need to add some extra field to the Contact us form?

Yes, I need to add some extra field to the Contact us form as described the other nopcommerce member to avoid spam.
