Is there some way I can stop spammers using my form?

Good Morning,

I got a notification that I've hit my limit for free submissions on my contact form. The problem I have is that one person has submitted the same spam piece over 200 times. 

I don't mind paying for something, but if I upgrade my account and this person keeps submitting the spam until I hit the limit again, I get no value. 

Is there some way I can stop it or have you help me stop it?

You can prevent spammers by adding Captcha in your form.

Or enable unique submissions in your form, this would let your user to submit your form once only.

Please give it a try and let us know if the issue still remains.

Thank you.
