This might be a feature rather than a bug, but anyway:

I did a long test post with the tag ‘test’, and then clicked “not spam” on the Akismet Spam page. The post then appeared on the site, but the tag was removed. (The tag still appears in the tag cloud, but doesn’t point to anything.)

I’m guessing Akismet strips tags since they’re an easy target for spam. If so, would it be possible for it to remember the tags for the sake of false positives?

When you click on the tag does it go to a 404 file, not found?

Nope; I think it went to a page to start a new post.

I don’t think it was designed for ‘undelete’ on tags. I haven’t test this myself, but there is a utility in the admin to delete tags on posts that don’t exist, so I was under the assumption that the tags stay even if the post is deleted. I have some time tonight and will test this further myself. If it deletes the tags with the recent TRAC version, then I can file a ticket for you.
