Personally I hate captcha's and much rather use some sort of security question. Something like: "Which number is higher: 12 or 15?"And people solve that, meanwhile in the background the answer field is called "email" so bots are fooled into giving the wrong answer.HESK (what I previously used) has such a feature. I can't find it in osTicket, which is a pity because the osTicket captcha is completely useless it seems.I get a flurry of web submitted tickets. With requiring registration as a last resort - What can I do to combat spam more effectively?
