Security check gone?

Post by RedGolpe »

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.

That's very useful feedback. Thank you.

You should not have received a 30 second warning if the page had expired. I've modified the script and that shouldn't happen again.
