### Security check gone?

I've solved a problem a few minutes ago and noticed that the 5-digit captcha had disappeared. Also on a new problem I checked, no captcha. Is this intentional?

Yes, it is quite intentional. Most users will rarely see the CAPTCHA now, but it will appear for a period of time if the system detects unusual patterns.

Nice idea!

I noticed something odd though: I usually keep the problem page open while solving it, and after some time I suspect the security check expires: before the change I got the message "wrong security check" or something. Now the page just reloads without any message and the solution is NOT submitted. Attempting to submit it again I get the usual 30 seconds alert. Waiting the 30 seconds, the solution is submitted without errors.

Thanks for checking this out.
