Let's at least keep this discussion factual. You can't "find an equal amount of number for both", because it's not there. I've already explained why your examples were wrong. All decent anime/manga/VN/LN databases use romanization guidelines that keep the long vowels.
It's mostly because it helps keep things consistent. Danbooru also used to do it; but this resulted in several tags using spellings most other users wouldn't use, resulting in counterintuitive searches.
The new adapted approach is supposed to use tag spellings more in-line with those of their respective fanbases... though this makes discussion of tag names much more complicated because we now need to 'quote' usage statistics and use examples on other websites. Most of the admins on the other database websites wouldn't want this trouble (and Danbooru didn't want either); best just stick to a consistent modified Hepburn instead of trying to suss out each fanbase's preferred romanizations. With exceptions made for spellings that everybody knows like Tokyo and Kyoto.

I'm not the one who wants to play this game, nonamethanks is. My previous post was solely to counter his examples, because they were incorrect. Personally, I consider this argument silly, it's way too close to the "Appeal to Majority" fallacy.
I think that we should have a clear and consistent set of guidelines and stick to it, regardless of what other website do.
I would agree in some sense that there is some... risk in just blindly following "majority trends", especially if it results in inconsistent romanization for terms and 'generic names' across copyrights that are otherwise identical in the original Japanese... but Gensokyo/Gensoukyou is unique (the name as a whole, not the individual kanji, like what NNT mentioned about Tokyo vs Touhou). If the fan wikis, fan-scanlation groups, Japanese doujin circle romanizations, Steam game descriptions, and the general Danbooru userbase all seem to prefer Gensokyo over Gensoukyou... then it is best to change the tag name over to Gensokyo.
