A while back our site started receiving a slew of spambot comments, eventually forcing us to take down the comment option for blog posts. I didn't want to place a regular Captcha solution, and after little sleep and much thought I came up with a new idea. And since every new technology needs a catchy marketing acronym:
introducing Slauth - Sardonic Lore Authentication

So what is Slauth?

Slauth is an anti spambot solution based on sarcasm, pop culture and cognitive deduction. It's meant to differentiate between well meaning humans that honestly just want to post comments and evil spam bots that want you to buy v!a@ra.

How does it work?

The user views an image and is required to complete a sentence\answer a question relating to that image. Since bots don't understand sarcasm, and have never seen Star Wars, their image reading algorithms aren't going to be of much use.

Why is it better than regular Captcha?

First of all, Captcha is annoying. It requires you to enter letters and words that sometimes even as a human you might fail to distinguish. Most importantly, Captcha is not fun. It feels like a chore and gets really frustrating when you don't get it right 

Where can I see it in action?

Right here! Try to add a comment to this post. 

Since we moved to Drupal, Slauth has been deactivated. It was a fun experiment while it lasted :(

Now for the fun part -

What I need from you is ideas for more images (questions and answers). The question has to be interesting and amusing, while the answer must be unequivocal and not too hard to spell. Just add your idea via a comment to this post. The good ones will get integrated into the system with credit to the contributor. Not only that but - the funniest\wittiest idea will win a free copy of our album!

so go ahead and send your suggestions.
