After the recent changes we made on how adverts must be viewed we have just made a couple optimizations to make those changes less troublesome.
1. The image CAPTCHA is no longer required on ClixGrid.
2. The image CAPTCHA for PTC Adverts still remains on all clicks but is now shown before the timer, not after. This will remove the stress of waiting on the timer. Now the first thing you do is click the correct image and let the timer work while being able to commit full attention to the advert.
