From this Uservoice Item:
If you look at this question there's a tag called 'ass-kicking' that no one can get rid of since the question was locked and moved to serverfault.com . I'm not sure what the resolution could be, but either:
- Allow 10Kers to edit locked questions to remove tags (for questions that have been moved?)
- Allow us to flag said questions so people that can remove tags or edit questions that are moved can do that.
The bottom line is that I don't think it's a good idea to create a system where I could potentially have a tag last forever because no one but 4 people can get rid of it.
