I don't want to limit the entry to once per IP, as we have a few repeat customers and they'd be blocked from submitting later on down the road. However, we've noticed an influx of spam, and I imagine once a spammer has filled the captcha out one time, they're able to repeatedly send through spam messages in that open session. </p> https://www.machform.com/forums/topic/captcha-is-somtimes-not-showing#post-18255 Mon, 13 May 2013 14:00:21 +0000 yuniar 18255@https://www.machform.com/forums/ <p>That is on purpose. Once a person has successfully submitted a CAPTCHA, we can be certain that he/she is a real human, hence MachForm won't display any CAPTCHA for any subsequent submissions.</p> <p>This is valid during that particular session only, for that particular user. If the person closed the browser or the session expired, the captcha will be displayed again for that person.</p> <p>We did this for usability reason and to increase the submission rate of your form. </p> https://www.machform.com/forums/topic/captcha-is-somtimes-not-showing#post-18244 Mon, 13 May 2013 04:49:27 +0000 emarioc 18244@https://www.machform.com/forums/ <p>Okay new update I had tried so many things was getting a bit confused. I went back to gmail now using 465 for the port. It did work the first time. However, when I attempted to use the form a second time from the site I found that it is not asking me for the simple captcha again????</p> <p>I am don't understand that. Is this normal? If I clear the cache on the browser and navigate to the form again I am asked for the simple captcha..</p> <p>Any ideas? </p> https://www.machform.com/forums/topic/captcha-is-somtimes-not-showing#post-18243 Mon, 13 May 2013 04:34:10 +0000 emarioc 18243@https://www.machform.com/forums/ <p>Okay, it would seem that it is all about the dog gone GMAIL!!!! Uggg., If I setup using one of my 1and1 accounts for validate for smtp everything seems to work as designed. </p> https://www.machform.com/forums/topic/captcha-is-somtimes-not-showing#post-18242 Mon, 13 May 2013 03:47:09 +0000 emarioc 18242@https://www.machform.com/forums/ <p>When I test my form I find that sometimes it show the captcha and sometimes it doesn't. </p>
