Уже четыре дня приходит через форму отправки одно и то же письмо от одного и того же отправителя. Хотим занести его в черный список по параметру e-mail, чтобы перестать получать эти сообщения.
Может ли это быть сбой самой формы отправки или это может делать только человек вживую?

To confirm you are getting multiple submissions from one person, is that correct? That is quite not possible because there's a back end code that validates the input. It is possible that this is more related the user's end.
You could do the following:
1. First, add a captcha field to avoid your form being used as a spam.
2. You can use the following widgets:

3. If you want to limit the submission by IP address or via it's cookies, you can follow this guide: http://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form
4. If you want to limit the submission by unique question, you can follow this guide: http://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question
I hope that helps.
