[nfbcs] Captcha

Tue Feb 28 20:03:38 UTC 2012

I'd have to see how the cold fusion solution works but I don't believe it 
can be done. Not for long. I suspect that the main reason the cold fusion 
solution, whatever it is, is effective is that spammers don't bother trying 
to break it because its just easier moving on. What possible way could a 
site distinguish a spam bot from a real human such that the spam bot 
couldn't get around it? I suspect cold fusion does something like grey 
listing where it simply encourages the bot to move on to an easier target. 
Or it uses something like spamassassin where several characteristics of the 
visitor are measured and if enough of them match the typical characteristics 
of a spam bot, its flagged as a bot.

But again, the bots can get around those things if they want to. I suspect 
one of the reasons the cold fusion thing is so effective is that its not 
very commonly used.
