I added comment A to a report in the Service. My colleague can delete comment A. She can do so as - owner of the (old) workspace - member of the (old) workspace - not a member of the workspace...

Community SupportHi ElsD,
Based on my test, if the user is a admin or has edit permission on the workspace content, then this user is able to delete other user's comments.
In your scenario, you can add the user as a member of the workspace with read only permission, or just share the report without adding the user as a workspace member. The user should not be able to delete other user's comments. Please let the user refresh the browser page after you change permission for a while.
Best Regards,
