user1908: I have been adding a number of partial names as tag synonyms recently. For example:

yahari-ore-no-seishun (from "yahari-ore-no-seishun-rabu-kome-wa-machigatteiru") and my-teen-rom-com-snafu (from "my-teen-romantic-comedy-snafu") as synonyms of oregairu
blood-blockade (from "blood-blockade-battlefront") as a synonym of kekkai-sensen
dungeon-ni-deai (from "dungeon-ni-deai-wo-motomeru-no-wa-machigatteiru-darou-ka) as a synonym of danmachi
soredemo-sekai-utsukushii (from "soredemo-sekai-wa-utsukushii"), world-is-still-beautiful and the-world-still-beautiful (from "the-world-is-still-beautiful") as synonyms of soreseka
yuuki-yuuna-yuusha (from "yuuki-yuuna-wa-yuusha-de-aru") as a synonym of yuki-yuna-is-a-hero
and many others that you can see at https://anime.stackexchange.com/tags/synonyms

I don't like doing this (these partial-name synonyms are incredibly ugly and I would much prefer to have more characters available for tag names), but I think that this is one good way to help ensure that low-rep users trying to ask questions about these long-named series are able to find a tag for what they're looking for. 
For example, it is entirely possible that a person who has watched Oregairu will not actually know that it is often abbreviated "Oregairu", and will instead try to type the title they know - either Japanese "Yahari Ore no..." or English "My Teen Romantic...". With these ugly partial-name synonyms in place, the odds they'll find what they're looking for is higher.
Does this seem like a good idea? Should I continue doing this? 

user7579: I support this idea, despite it being a monstrous, horrible hack.
I read your answer on the Stack Exchange meta post arguing for longer tag limits (here it is for anyone who hasn't seen it) and agree with everything you said. I don't see why it would be a problem to have tags go to … after 25 characters if having long tags creates some layout problem. I suspect the 25-character limit was just a decision the developers made early on for expediency, which has now become a problem.
On the other hand, I'm somewhat pessimistic that what I would expect to be a rather large change to the code will be made on behalf of a tiny site like Anime and Manga, or even a larger site like Movies and TV. I suspect this hack is what we're going to be stuck with. And it is better than having the "official" abbreviation be our only tag name, especially when the "official" abbreviation is as bizarre as these:

Boku wa Tomodachi ga Sukunai is "Haganai"
Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui! is "Watamote"
Yahari Ore no Seishun Rabu Kome wa Machigatteiru is "Oregairu"
Saenai Heroine no Sodatekata is "Saekano"

It looks as if they just picked some random syllables during a linear sweep of the full title. At least if tomodachi-ga-sukunai is a tag, I can type part of the title into the tag search bar and have something pop up.
I fear that we're stuck with this for now. I guess if Stack Exchange won't grant our request for longer tags, we could try lobbying the anime industry in Japan to pick shorter titles that would fit in 25 characters.
