Iv'e got spam in my form

Iv'e got this submission in my form:

It's a campaign lead collect form so I don't wanna use capchas. Don't you have some antispam algorithm in your forms which dismiss such a simple spam issues?

Yes, we do actually have anti-spam checks that detect when a submission is being made by a script or a bot, and prevents them from submitting your form unless they fill out an additional captcha field.

However, humans can still submit your form - even if their entry is a spam one. In other words, people can still make spammy submissions on your forms manually. If this happens on your form frequently, you may want to set a Unique Submission Form Limit to prevent multiple submissions from the same IP.

Other than setting a form limit for unique submissions, we only have captchas as an option, but people could still manually fill out a captcha to make a spammy submission on your form. Some of the less obtrusive captchas that are now becoming popular are available as widgets, such as:

Google reCAPTCHA (demo form: http://form.jotformpro.com/form/50058467346964)

PlayThru CAPTCHA (demo form: http://form.jotformpro.com/form/40726238648966)

Drawing Captcha (demo form: http://form.jotformpro.com/form/41613144428954)

I hope this helps.
