Hi guys,

 

Can you confirm what i have done is sufficient to stop spam.

When the page loads:

@{

    Layout = "Layout.cshtml";

    int aNumber = new Random().Next(1, 3);

    int bNumber = new Random().Next(1, 11);

    var errorPrintOut = "";

    bool contactSent = false;

}

 

The numbers are displayed to the user to add:

<label id="captchaCheckLabel" for="captchaCheck">@aNumber + @bNumber =</label><p style="color:red; font-size: 20px;">@errorPrintOut</p>

 <input type="hidden" name="nA" value="@aNumber" />

  <input type="hidden" name="nB" value="@bNumber" />

 

The user submits the form and:

 

@if (IsPost)

{

    var capchaCheck = Request.Form["captchaCheck"].AsInt();

    var nA = Request.Form["nA"].AsInt();

    var nB = Request.Form["nB"].AsInt();

 

    if (capchaCheck == (nA + nB))

    {

        //send email

        contactSent = true;

    }

    else

    {

        errorPrintOut = "Sorry that was incorrect. Please try again.";

    }

}

 

In esence will this stop spam bots or not?

 

Kind regards.
