I tried to post a question on the site, and received a message to the effect, "you can't post anything else until 40 minutes are up."
In fact, I hadn't posted anything for three days. (I have two posts on the site.) But prior to posting, I had conducted some "searches" which may have been mistaken by the system for posts.
I haven't encountered this on other SE sites. Is this feature peculiar to Open Data or is it a function of my low rep on the site? What is the rationale, anyway?
And why might the system mistake my searches for posts?
