According to the create new tags privilege page:
However, note that:
- on some sites, new tags will be automatically culled and removed from the system if they are not used by at least 1 other question in a 6 month period.
How does this happen? Is it an automatic revision from Community♦? Are the revisions actually edited so the tag is never shown (highly unlikely, but I don't know)? Or does it come in some other form?
I'm asking simply because I've never seen any auto-edits by Community♦ that remove unused tags, which makes me wonder if that's actually the way removing unused tags is accomplished.
