Better explanation when account is blocked
A few months ago SO started blocking questions from users with a history of poor questions; users get the error message:
Sorry, we are no longer accepting questions from this account.
It's not clear to users who see this what they did wrong, or how to fix it, so they end up posting the error message on meta (1, 2, 3, 4). Is it possible to include an explanation in the error message, or make it link to a meta post or FAQ section that does? It's particularly important to tell them what they can do to fix the problem -- I'm not even sure what the answer to that is (post answers that get upvoted? e-mail team@?)
