I haven't seen anything on the group or otherwise for a basic house- cleaning method for getting a list of suspended/canceled/deleted Twitter accounts. As our Twitter apps continue to grow, having methods for clearing out the dead wood from our systems would be quite useful. I don't think anyone wants to end up a few years down the road with a million non-existent Twitter accounts in their system, and I don't think it helps Twitter to have traffic coming back to them for accounts that no longer exist.
What I propose is a simple method for grabbing the Twitter IDs of those accounts which have been permanently removed. If we could have returned an array of these ids (much the same as the new Social Graphs methods return only the IDs of a user's friends or followers) it would help us all keep our systems clear of these defunct accounts. Perhaps options for a since_id or since_time would also be useful so we only get the IDs we haven't already cleared out. Thoughts on this?
