Over the past week or so, I've seen many questions from users who don't understand why their accounts have been locked.
They have even made the effort to come here and ask why, so at least they know something about how things work. But they still don't understand why their accounts have been blocked.
Users who go to the effort to post here are not drive-byers and are interested in being reasonable members of the system.
I suggest we provide a link with the block message to indicate how users could retag or change their questions to attract some votes or otherwise be allowed to participate again. (Maybe the link should also include information on what constitutes a good quality question.)
