I understand the purpose of the human test to prevent spam, but often times I get it perfect and it still says I have to pass the test. This is extremely frustrating when I have a long comment and can't retrieve said comment and have to type it all over again. Sure I can copy the message before pressing send, but I'd prefer if you have this human test you at least get the bugs out of it. And yes I'm 100% sure I typed the text exactly for the test. It's just annoying.
