The "add dice up to 14" captcha - five times in a row - with a time limit - grainy images - that resets if you get one single wrong answer is absolutely not a test of me "being human". It is a frustrating and ridiculous waste of time that is not disability friendly and simply impossible under some internet conditions. Personally, I already detest dropbox and only use it when forced to by external collaborators. Every time I am forced to use it there is some fresh ****** you have invented to make the experience even worse.
Doing fieldwork where I had patchy internet and a small screen this captcha was impossible for me. It delayed file sharing for about a week. Get rid of it. I can only imagine how impossible this must be for someone with dyslexia, and there doesn't seem to be any way to ask for an alternate test. Frankly I can't believe someone hasn't sued you for discrimination yet.
