I recently added a lot of posts into my public favgroups with a tagscript. And I upvoted some previews with a tagscript.
My change history shows that I would have added tags bad_source and bad_link to some of them. I have never written either of these tag names, and they have an inconsistent order in my history. I recognize the posts and they do have the favgroups and upvotes I have given them. E.g. post #221834
What was my mistake?
