database log full of DELETE FROM .. komento_captcha where INTERVAL 12 HOUR

Hi StackIdeas,

I am not sure but looks like I have found an issue in the component.

today I have found on my server following query is being executed multiple times per second:
DELETE FROM `_komento_captcha` WHERE `created` <= DATE_SUB( '2016-10-06 19:47:42', INTERVAL 12 HOUR );

I see in the code that you have implemented 2 queries for cleaning captcha - one with interval 7D and second one with 12H. I see as well that komento cron tab and the setting "clear captcha on page load" are triggering the query with 7D.

But I can not understand who is calling constantly the query 12H in my database. I see this query in php code in administrator/components/com_komento/tables/captcha.php but can not understand why and how is called constantly in my installation?

I see in my Apache log a well a huge number of POST requests "POST /?option=com_komento HTTP/1.0".

please help

thank you in advance
Martin
