This is the second time I have created the community-bulletin tag: chat.stackexchange.com/transcript/10243/2017/9/17 However, I deleted the previous question - since in the previous instance I realized it was a network-wide issue and I posted it on Meta Stack Exchange instead.
The examples I was able to to find are from Stack Overflow. From what I read on their meta, it seems that hidden-features and code-golf are blacklisted - although they still exist on some questions.
In fact, in both cases the tag-wiki explicitly says the tag is currently blacklisted.
Right now? Just sql.
There is guidance associated with a few other tags... But those tags are blacklisted - you can't submit the question if you use them. Currently on Stack Overflow, google, hidden-features and code-golf fall into that category.
There are posts on their meta showing examples what happens when somebody attempts to use such tag.
You point out something I'd forgotten about: we never blacklisted this tag. I've remedied that:
Given these questions cannot be edited, this serves to preserve the categorization of those in the archives while discouraging folks from posting new ones.
The remaining questions are a part of Stack Overflow's history. Or mistagged. Either way, there's no particularly good reason for using this tag on any new questions, so like hidden-features before it this is now blacklisted:
Blacklist items automatically expire if they are never triggered for some amount of time. It's possible no one tried to use it for too long. — animuson ♦1 min ago
We'll see whether we'll find out more details about that.
I think it might make sense to make polytopes a synonym for convex-polytopes. Although non-convex polytopes are sometimes studied, convex ones are much more prevalent. Also there are only 36 questions tagged "polytopes" while there are hundreds tagged "convex polytopes."
