Rare occasion. I actually have two questions about Apple products and it complains
I don't quite understand the rationale whichever way I think about it. Even if this is something to deter spammers, am I expected to turn into a spammer on an individual SE site suddenly, although having gained rep on several others already?
To add insult to injury I was handed a CAPTCHA on the last attempt. Perhaps because I kept retrying to post the question? Although, I kept retrying because there is no indication of when the 20 minutes are through?! ;)
