Is it possible to check whether a tag have been removed by this process (because of being used on a single question)?
- If I remember the name of the tag, can I find out how it has been removed - manually or by the system?
- If I remember a question where this tag was used, can I somehow check whether a tag has been removed from this question by this process (and not manually)?
Here is a specific example. As mentioned here on meta, the tag finiteness has been used in this question. If I look at the revision history, none of the edits show removal of this tag. The first revision of the post is shown without tags. This seems to be different from the behavior of a tag which has been removed manually, for example, you can compare the revision history and the first revision of another post, which uses a tag which no longer exists.
