 - If the captcha is resolved in less than 1 second, it's not valid.
-- If the captcha is resolved in more than 1 minute, it's not valid.
+- If the captcha is resolved in more than X seconds, it's not valid.
 - The images url, are UUIDs generated each time, in order to give different names for the images each time.
 - The ip of requested captcha and answered captcha petitions must be the same.
 - Each time a user fails answering the captcha, the server adds a counter to the IP and stores in to MongoDB. When the counter on that IP is greather than the value 'suspiciousIPCountLimit' defined in serverConfig.json, the IP is blocked for 'timeBan' seconds, also defined in serverConfig.json.
