On Scifi.SE, the tag cleanup script is disabled. This means that when a tag is used once, it no longer is automatically deleted after 6 months. However, what happens to tags that are now defunct/unused?
The example I have is little-league, which is the former name of a web-comic. Said web-comic is now named JL8, so I made a JL8 tag and edited the one question to use it. But it looks like the little-league tag still exists.
Will a completely unused tag get cleaned up automatically? As a diamond mod on scifi.SE, is there something I can/should do to clean up that tag?
