Re: Should we really care??

I read that somebody suggested that you would get a pop up that shows i.e. a car and then you get 3 choices like a) book b)car c)plane. Unless the options are in a lot of languages this idea is not good, I know people playing on Party who do not even know what book is in English. However, couldn't they pop up a picture of i.e. a car and then you would get an option of choosing between 3 different pictures of which one is of a car (different angle, different color of course). I think it would take computer programs decades to beat this.

Any challenge program you can think of doesn't work. The bot programmers (or whatever else you are trying to protect against) can beat this easily. The clever way I've heard of late is you have a site where you show free porn to people who answer the questions for you (I.e., you forward the challenge to other people). There are lots of people at any one moment looking for free porn and if they have to match a car picture or type a hard to read word/number sequence that is pretty trivial to get someone else to do for you.
