Question: [semicolon-#](https://codegolf.stackexchange.com/questions/tagged/semicolon-%23 "show questions tagged 'semicolon-#'") is a tag for challenges related to the language `;#`. I suggest we remove this tag, since it is very localized and we've pretty much exhausted all non-duplicate challenges concerning this language and derivatives thereof. I predict most of the future challenges that could possibly be tagged with this tag would either be a duplicate of a previous language-implementation challenge or just a poor challenge in general.

Answer: 
Lets remove some other language tags too
========================================

I have noticed a large number of language based tags that are only attached to one or two questions. Particularly a large number of tags only attached to a [tips](https://codegolf.stackexchange.com/questions/tagged/tips "show questions tagged 'tips'") question. And if we intend to get rid of [semicolon-#](https://codegolf.stackexchange.com/questions/tagged/semicolon-%23 "show questions tagged 'semicolon-#'") we should get rid of some other seldom used language-based tags.
Get rid of it
=============

;# produced some interesting challenges that, while they benefited from being related to the language (the ridiculousness of language itself pushed it far), could definitely have been standalone and unrelated challenges.

;# is also a valid language *only* for [kolmorgorov-complexity](https://codegolf.stackexchange.com/questions/tagged/kolmorgorov-complexity "show questions tagged 'kolmorgorov-complexity'") challenges. This makes answers in the language a very rare occurrence. Other languages (such as [python](https://codegolf.stackexchange.com/questions/tagged/python "show questions tagged 'python'"), [java](https://codegolf.stackexchange.com/questions/tagged/java "show questions tagged 'java'"), [jelly](https://codegolf.stackexchange.com/questions/tagged/jelly "show questions tagged 'jelly'"), etc.) have their own tags because:

1. of their tips questions.
	* ;# cannot possibly have any tips, since any task that is possible in it is solvable in one and only one way.
2. parts of the language can be explored to make challenges about.
	* ;# has exactly two commands which have been explored *completely* in the few challenges done.

Furthermore, any more challenges could only possibly be "extensions" of the language, which has been shown in [:$](https://codegolf.stackexchange.com/questions/122289/without-resetting), [+-#$%!](https://codegolf.stackexchange.com/questions/122343/make-a-interpreter) and [;#\*:)](https://codegolf.stackexchange.com/questions/141055/make-a-interpreter).
