Can I ban an IP address?

Hello there!
For the past seven years on the internet, I have had to deal with a troll/stalker on various platforms. I am an internet streamer who gives advice to many people using jotform now. This person who badgers me has now asked me several questions and is spamming me. Is there any way I can block their IP address? I do not want to take away my ability for people to be anonymous within my jotform, but this guy has a way of speaking that is noticeable and repetitive that I always know who it is, and many times he uses his actual name. I am just trying to have peace of not having to deal with him. Please give me any clear answers. Many of his questions have things to do with getting in my pants.

There's no way to block someone from your end per se but there's a way to limit spammers from submitting your form multiple times.

1. If the spammer is using an automated program (or a bot) to spam your form, we recommend you add a CAPTCHA FIELD.

2. If it's an actual person spamming, you can limit their form submission based on their IP or cookie, or both.
