What type of captcha will you recommend? I am looking mainly at usability, ease of use (development too), relatively secure
I find that those captcha with very curly words/numbers are sometimes too unreadable. What I start to see in many applications are simple calculations "Whats 5 + 15". seems simple, but that should be easily crackable by bots, i'd expect?
I am not working on a very secure app, u know just general web apps like project management, forums etc type apps. So I don't require hard core security which I think will be overkill and just mess up the code. I prefer something minimalistic & easy to use
I read about honey pot method too. Where I have a input thats hidden by css. The theory is that bots will fill up all fields. How true is that? That is simple to implement least intrusive, user does not need to do anything. Does it mean that I can just have that without captcha?
