I saw the below message just now when about to ask a question on the site:
Wait! Some of your past questions have not been well-received, and you're in danger of being blocked from asking any more.
For help formulating a clear, useful question, see: How do I ask a good question?
Also, edit your previous questions to improve formatting and clarity.
The problem is, from what I can tell on my profile for this site, I have exactly two questions that I asked about 3 years ago, both of which have positive (yet low) votes. One was left without marking an answer as accepted, so I took the liberty of doing that right now.
So what justification might there be for blocking my account based on two fairly benign questions?
