"Prove you are a human" game is hidden by AdBlock

There is a game to prove you are a human.
However if you are using AdBlock (https://chrome.google.com/webstore/detail/adblock/gighmmpiobklfepjocnamgkkbiglidom, the most popular Chrome extension with more than 15 million users) the game is not visible, so newcomer can't register.
The error message is "You didn't pass the game", which is not very informative in that case.
Should be something like "You didn't pass the game, try disabling AdBlock to see it". The best solution would be making the game visible anyway.

Tested in Google Chrome
