That would take the feature a lot farther than our current intentions. Right now it's a single field in the DB (along with a timestamp tracking when you last updated it). You'd have to have a kind of history to show the last status update that they submitted before being suspended, or you'd have to complicate the SQL query to check if the user is suspended (and the way status data is stored, that isn't a "simple" query). Ultimately, you do want your board index page to be fast, so we don't really want to add a lot of heavy queries where they're not necessary.
Of course, saying all that, I intend to look into adding the ability to edit the member's status and about me text from the edit member page on the front end soon. Most people causing problems (or spam accounts) tend to update Website, Status, About Me, and/or Signature. You can only fix website and signature from the front end currently, so giving you the ability to edit the other 2 should help make things simpler.
