I am receiving a lot of spam by individuals (not machines) What can I do?

I already use a CAPCHA, but since the spam is done by an individual, this doesn't work.

They use a different IP Each time because they use an anonymous browser, but I know it is the same person each time.

What Can I Do?

Thank you!

Hi,

Please send us the list of the IP Address so we can ban those from our system. You can also ban the IP or the IP Range to your cPanel (if your hosting uses this). Follow this guide: http://docs.cpanel.net/twiki/bin/view/AllDocumentation/CpanelDocs/IPDenyManager#Deny an IP address

Thanks

Hello.

The trouble is, they are using tor, which is an anonymous browser, so their IP changes each time they log on, so this would not stop the spam

Thank you.

Hello clickcom,

Please be noted that having captcha fields in your from will be effective if there is a automated attempt to send spam submissions. But if there is a human attempt to send spam message, captcha field will not be effective.

Apart from my colleagues suggestion, you can also use our "Unique question" feature which will prevent duplicate submissions in your form. Here is a guide to help you:  http://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question

If you set one of your form question as "Unique question", it will not allow someone to use the same data in that field to submit the form twice. Example: You can set one of your forms question (like cell number or email address) to be a unique question. This will not allow a user to use the same cell number or email address to submit your form.

Hope this helps.

Do get back to us if you have any questions.

Thank you!

Hello.

If I set the unique question as email, what if someone wants to submit the form with non-spam questions?

For example, I have people who regularly submit the form with non-spam questions.

Thank you.

You can use the option from Unique submission which is Loose Check so this doesn't limit your legit user from sending a single submission per IP as this limits validate base on cookies. Also use the captcha field as adviced by my colleague in his previous post this will also help from spam messages.
