    Hi,

    We are sorry for the inconvenience issue.

    You can take a couple of security measures to prevent SPAM.

    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 setup the form to have a Unique Submission limits. Under Setup & Embed->Preferences->Form Limits.

    Loose Check-> Limits the computer/device where the form is being filled out using the current the 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.

    3. Another way is to have a custom hidden field to where the Bot Blasters will fill out automatically without knowing.

    3.1 Add a textbox field, in my case its named "hidden check". This will not be filled out by the user.

    3.2 Under "Setup & Embed" click the "Conditions" setting to add a rule or logic in your field. Choose in the Conditions Wizard the "Show / Hide a form field".

    3.3 Here what we are saying is that, if the "hidden check" is filled, the "Submit" button will be hidden, thus preventing the form to be submitted.

     

    I hope these methods would help or give you an idea. 

    Let us know if you need further assistance or your problem persists.

    Thank you.

    I've been receiving the same Russia spam, not through jotform but from my website forms. I got the same message that is noted in this question. 

    It's been going on for 4 weeks

    Hi again,

    When I check your website, I can find a form which belongs to Jotform. Its title is "Publiedi CONTATTI" and it is associated with the account "cagnoleo".

    If you embed your form to your website which is created in Jotform, your submissions will still continue to be sent from us, not from your server. So when you embed the form to your site, you don't drop the relationship of the embedded form with Jotform. Your e-mail service is still from Jotform even if it's embedded in your website. 

    So I'd like to recommend the owner of the form to add CAPTCHA widget to the form which is titled as "Publiedi CONTATTI". But if you have this issue with an another form, please kindly give us the form ID. 

    Kindest Regards.
