Once in a while, I encounter this problem, too. When friends 
send me their tagged fotos, digikam happily imports their 
tags (from image XMP), too. Since everybody uses different 
tags, this somehow "polutes" my tag tree.

My workflow in those cases:
  1. Go to the album, which contain the newly imported
     pictures from my friend
  2. select all pictures
  3. in the right side view "Captions/Tags" I enable the
     button "[view] Tags already assigned"
  4. uncheck all checkboxes (to remove the tags from the
     fotos)
  5. "Apply"

This removes all tags from the fotos, but the tags remain in 
the tag tree.

  6. I go through the left side view "Tags" and delete all
     tags, which are assigned to 0 fotos (the number of
     fotos which have this tag assigned can be seen in
     braces after the tag name (e.g. "Uncle Jon (5)").


Feature requests:

To speed up this process, the following two ideas came to my 
mind:


a) "Delete all tags of a foto with one click"

This function could be added in the right side view 
"Captions/Tags" as additional action at the "More"-button.
With safety query "Are you sure to remove all tags from the 
selected fotos?"
This would speed up step 4.

b) "Delete all unused tags"

In "Tags Manager" -> "Organize" one could add a new function 
"Delete all unused tags".
This function would collect all tags, which
    - are not assigned to a foto
    - and have no child-tags (or only unused child-tags)
This list would be presented to the user:
   "Do you really want to delete the following tags?
      - sample tag 1
      - sample tag 2
      - ..."
This would speed up step 6.

Just my thoughts about this topic.
