Currently the script it is very simple and it is not spam-bot-proof, but the next version – server controlled – will be. I’ll release it with some sample games.

Actually, we don’t need it right now because the password quality (measured in bits) is a strong enough deterrent for spam-bots. But we use it mostly to prepare users to the similar visual pattern that they will find when they will connect to PassPack in the next time (it’s similar to the anti-phishing screen).
