I've recently launched the Q2A website https://onesharedearth.com
and in the last couple of days been bombarded with spam. So in the "Spam" tab, I enabled "Use moderation for users with less than" 150 points and deleted all spam posts.
However, the spamming users had also added lots of irrelevant tags. Now my "Tags" page is showing links for 3 pages even though only 1 tag is present. How do I delete the other tags which seem to be hidden but still are interfering with the "Tags" page? See https://www.onesharedearth.com/tags/
On the same note, are the posts that I deleted (after hiding) actually deleted from the database or still using up space in my database?
