User:Startle Stars/Duplicate categories

This is a list of frequently duplicated tags; instances where someone tags a fic with a tag that is similar to, but not quite, the correct tag, and hence ends up creating a duplicate tag to describe the same thing. One example of this would be referring to Category:Dubious consent as Category:Dubcon. This list helps quickly locate any potential use of duplicate tags so that they can be corrected. The incorrect duplicate is listed first, the correct tag is listed second. If there's a reasoning for this, it's given after the second tag.
