    DOS Attack

    Asked by SunnyGee on January 04, 2013 at 11:52 AM

    We just received more than 100 entries for one of our form within 5 seconds. Is your service not prepared for DOS attacks or spamming?

    Regards

     Hi,

    We are sorry for the inconvenience this has caused, those unwanted submissions are probably done by spam or spam bots that are able to see your form especially if its embedded on a website that had been targeted by spam previously.

    The most known way to block and prevent this spam is to add the Captcha field found among the Power Tools. 

    At the extreme you can also use the secure URL protocol when embedding the form. Although please take note that since you have a free account the SSL submissions limit will only be 10 per month.

    I have also reset your monthly form submission counts. So, you will not go over your limits.

    Thank you.

    In addition to what Moonzkie has stated to you, yes, we are prepared for that, if we noticed that within an hour the form recieved a certain number of submissions, we will get an alert and our automated system or our Form Reviewers Team will disable that form
