Recently it was decided that the autograph-identification questions are no longer on-topic - as a result of the discussion here: Revisiting autograph identification questions (conclusion: off-topic).
As far as I can tell, so far the only thing that was done as a consequence of this was adding a sentence mentioning that the the questions of this type are off-topic into the tag-excerpt and tag-wiki. (Certainly some users read the tag-wiki before using the tag, but it is quite easy to overlook and many users who ask a new question and use this tag might simply miss the information given in the tag-excerpt.)
Are there some further steps that should be done in order to better handle the fact that the tag is now deprecated? Should something be done with the tag? Should something be done with the existing questions?
There is a related question on meta (which is intended to be general - not about one single tag) and there was also a short discussion in chat about this tag. Various suggestions of various steps that might be useful were mentioned there:
- Historical lock on the existing questions. (This would make clearer to a user browsing the site that questions like this are no longer on-topic.)
- Blacklisting the tag. (This would prevent adding new questions with this tag.)
- Burninating the tag. (This would remove all occurrences of the tag in existing questions.)
And probably there are some other things which possibly might be useful.
Question: Would some of the steps mentioned above be useful? What would be advantages/disadvantages? Are there some other things that should be done?
EDIT: Comments such as this one suggest that some users might consider the existence of the tag as indication question about autograph identification are on-topic and they are then surprised that the question is put on-hold/closed as off-topic. (Since I assume that this particular question might be later deleted, either manually or by roomba, I have added link to a copy of the comment in chat. For users with sufficient reputation to see deleted content, here is also a direct link.)
