Based on this answer, [history] (as well as any other tag beginning with the word "history") is supposed to be a blacklisted tag on the main site. However that has apparently failed. This may not even be the first time it has failed as the tag was supposed to be blacklisted 6 months earlier (at that time blocking anything even containing the word "history" rather than just beginning with that word) but for some reason the issue reappeared then and has reappeared again now.
The tag has showed up again and is now present on almost 50 questions. I am requesting:
- The tag be automatically removed from all posts; and
- Whatever issue caused the blacklist to fail to block this tag's creation and use is corrected.
