How to prevent Spam submissions in Form?

I currently use JotForms for work and within the last couple months, I've started getting spam jotforms with random text. I've received about 4 spam forms and I'm not sure how these are getting submitted. I've attached a screenshot of one of the spam forms.

You can follow the suggestions below:

1. Using the Captcha field in the form editor. This is the most common and efficient way to check if the person doing the submissions is a real person.

2. You can also set up the form to have Unique Submission limits.

Loose Check-> Limits the computer/device where the form is being filled out using the current cookies being used. This will prevent to do multiple submissions unless they clear their cookies or use another web browser.

Strict Check-> Limits the computer/device where the form is being filled out using its IP Address, to where one IP can only have one submission.
