Advantages of using hidden fields in ColdFusion

Hidden form fields can be used in a good way for avoiding the spambots.  Spambots  are automated computer programs designed to assist in the sending of spam. If we have a hidden field in the form, user cannot fill the hidden field, but the spambots can do fill the hidden fields. So for avoiding this, we can have a hidden field say, <cfinput type="hidden" name="spm_inputcheck" value=" "> and we can have a condition like: <cfif form.spm_inputcheck is " ">     perform the actions.. <cfelse>     abort </cfif>
