[pchelpers] Re: News:Spammers beat new Microsoft CAPTCHA defences

I read quite a bit on Captcha breaking recently, and any of the ones 
that rely on pictures of distorted letters just aren't working anymore. 
There are a couple of new methods that use pictures of animals like cats 
and dogs, and ask the user to select the pictures of just the cats, 
which seems to work much better than the distorted letter method.

I'm sure that there are other tests that would work as well.

Good advice is like good paint- it only works if applied.
