Ah yes, very clever indeed! I like it!

Of course you know the spam bots will cotton onto this after a while!

My old saying applies, 'Make something foolproof and they'll just invent a better fool':)

Methinks it will be a while till they get around this one! Where I spotted it, its only weeks old, so relatively new. Can a spambot read left to right (normal), then repeat back the catchpa in reverse? I have not heard of it yet.

Definitely, it's a game of cat and mouse and there is no silver dart.

Seannie, we can't apply this here because we have a non-standard captcha which is doing a pretty descent job.

It's a change of one line of code in a bot to get around this. As soon as this technique takes off it will be instantly solved by the bots. It's nothing but a stop-gap.

If it ain't broke, then don't fix it! It does work very well, but a few spammers still get through. It's not affecting our workloads like the way it did before though. :)

If enough people use this trick the spammers will write code to try the captcha code forwards and backwards. Sure if they do you can re-write your code to do something unique like tell people to only use every second letter or something like that! Lots of possibilities using that method to stay ahead of the game.

Good find Seanie.
