I appear to have a question ban that has persisted for over a year, and has not reset at the six month stage. The majority of my questions have been neutrally or positively received but there are three very slightly naive questions which were downvoted (two very heavily, perhaps even draconianly).
Since it is my understanding that the software resets itself every 6 months it feels as if there must be a bug. None of my downvoted questions were poorly written, badly formatted or in any other way negatively contributing to the site.
I also recently received the 'popular question' award for one of the downvoted questions.
