When The Use Of CAPTCHAs Goes Wrong

Previously I wrote about managing your comments. One of it was using CAPTCHA. This, however, is taking it far too secure and hard to read. If it makes it that difficult to read in order to input, then how to verify? I have come across such sites and no longer go there because I can’t understand what they want me to input. It looked like an ‘M’ to me but it’s not, it’s actually ‘NN’. Sheesh.
