An old question on Super User with lots of views was just bumped by a spam user. The post was spam-flagged and removed, and the question was simultaneously protected.
Does this mean this related question is status-completed? Is there any other criteria for auto-protecting or does this happen when an answer on an old, popular (metrics?) question gets spam-flag-removed?
For what it's worth, I thought I saw a similar behaviour yesterday, but I was not sure.
