, but a petition to kill CAPTCHA will do about as much as petitions to end wars and hunger in the world - for the same reason. The reality is that the problem of spam on the Internet is very complex and there is no perfect solution. Saying "we don't want this solution" will not make the underlying problem go away.

I left the site for a while during the recent spate of CAPTCHA problems. We all hate them and find them frustrating to varying degrees. However, if there were no CAPTCHAs at all the site would be overrun with spammers. Every forum and thread would be full of posts for cheap nike shoes and viagra. It wouldn't be possible to see the valid posts amongst the fog of automated spam and the site would likely crash under the weight of the spam traffic. The site went through a phase a few months ago where an automated spammer was creating somewhere in the region of 1000 new member accounts every day - just to put links to spam products in their profile! Changes were made to the site, tightening up the CAPTCHAs necessary to join and they helped to stop the onslaught.
Until / unless a suitable alternative to CAPTCHAS is found; they are likely to be around and annoying everyone for many years to come.
