Just to make clear what the appropriate process for dealing with tag-removed...
Whenever you see such a question on the front page, do not hesitate to remove the tag!
Since this tag mostly occurs as the result of an inappropriate tag being purged from the system, associated questions are often (but not always!) rather poor and destined to automatic deletion after some time. If you feel the urge to cleanup some questions with this tag, it is recommended that you start with the oldest ones (last page of the newest listnewest list) since you will find a higher density of good questions there.
