that is the question. You've seen it I'm sure. The little image of letters where you need to type in what you see. Supposed to make sure that it's an actual person and not a bot, lessens spam postings on the forums. It's something we're thinking about implementing.
2 main problems. One is that these are easily cracked if they are simple. Thats why you'll find many of them that are very hard to read. If they are hard for a human to figure out it's less likely a bot can figured it out.
The second is it locks out the blind as screen readers cannot read them. Lawsuits have already been filed over this. So if we implement it as is, then it would have to be optional so the admin could turn it on at their own risk.
An alternative to this is to make an question/answer list. We'd throw some in by default and the admin could customize these as necessary. Screen readers could read them, so the blind could still access the site. Things like. "How do you spell blue?". "What color is an orange?", etc. Nothing too complicated since if you ask someone, "What is the capitol of Ohio". Many people might not know. This obviously has it's own set of problems where someone with enough time could sit and get a list of all your questions and answers and script their bot to answer them.
Either way is imperfect. But you guys are the ones that will actually be using it, so we'll get your thoughts and suggestions.
