This happens to me many times and I think it's boring. The human verification page prevent me to post an answer and it takes a long time for that the captcha box appears (perhaps it was because of the slow connection? I don't know) and this takes a long time to the point that I think my answer may become useless. I wonder if this check is essential and if it happens that a script can cause problems for this site so to think making this precaution (script). If this is the case I suggest just that verification would be smarter and it senses that I just posted an answer to help people and not something else.
