1. I think we should be striving for more tag specificity and move away from oldbooru-style broad category tags that apply to hundreds of thousands of posts (or a million of tags in the case of hair ornament).
Tag specificity is fine. This is a disingenuous takeaway from my BUR; I'm not arguing that the only tag we should use for hair ornaments is hair ornament, just that extremely specific accessory tags like these serve no purpose beyond tag padding. For example, apple hair ornament is perfectly fine, but a hypothetical toad in the hole hair ornament would likely only ever apply to the one character it was designed for.
2. Nuking a tag because only a couple of characters dominate it at the moment is very dumb and short-sighted argument and not only is akin to nuking any of the touhou character-specific ornaments back during touhou domination or stuff any of the waifu-of-the-month-of-the-gacha-of-the-year specific tags that turn out to be more common down the lane.
3. This kind of thinking is dumb and short-sighted and it is a the source of many of the problems that we keep stumbling into time and time again
and that as others pointed in discord it leads to a tag being nuked because "is just tag padding and that only applies to a single character and is just an alias search for that character", then a second character pops up and we still don't tag it because we have arbitrarily decided that 2 characters is not enough and then a third character comes out and then no one wants to garden it because by that time it's several thousands of posts that no one wants to sit through, so having a tag that can be considered padding seemingly applies to a 1 or 2 characters as of now is the lesser of 2 evils.
In the Discord server, the example tag you specifically brought up was the tokin hat, which is completely different. Tokins are historical articles of clothing that have existed for centuries before Zun was even born. While a majority of tokin hat is Touhou because of a certain popular character's design, it's completely reasonable to expect non-Touhou content to also include tokins.
The monocle hair ornament, however, is something that was introduced to the world at the same time as the one character that wears it, and that's not a coincidence - it's not generic, it's not common; it's extremely specific to the point that the only other post brought up in this thread is just a second example of the exact same situation (and looking at it, it actually seems more like a case of eyewear on head rather than a hair ornament). For decades, this object simply didn't exist, and when Watson Amelia fades into obscurity it's quite likely we will never see it again. What we then end up with is a junk tag, which is quite literally just a search for watson_amelia hair_ornament.
The "what about when another popular character comes out with this kind of hair ornament" argument is a good argument - for the more widespread and popular shapes/designs for hair ornaments. I would bet real money that in the next year we get at least one new character who's decently popular that sports a star hair ornament. However, I would bet even more real money that in the next decade we don't get even a single character, popular or otherwise, wearing a traffic cone hair ornament, or an oboe hair ornament, or a computer tower hair ornament. And this doesn't stop at just hair ornaments - this concept expands tenfold to all kinds of accessories, even to prints. I would fight just as vehemently against taco belt buckle, coffee pot earrings, worm shoelaces, or (god forbid) corrugated galvanised iron sheet print. If we encourage such tagging, we will look back in ten years and find hundreds of these garbage accessory tags with literally no overlap outside of a single character.
4. I believe this BUR is quite biased and came out of your personal distaste for vtubers and their fans/uploaders/taggers, you can keep denying it and calling ad hominem all you want, but the only reason you bring up monocle hair ornament is because of watson amelia and you didn't notice more egregious examples like snake hair ornament being 98.12% kochiya sanae with only 294 out of the 15671 being other characters (with 58 out of the remaining posts being nagatsuki posts coming from a single pool) until I brought it up, and you wouldn't be making such a fuzz out of character-specific tags if it wasn't more associated with vtuber tagging.
I know it might be hard for you to believe this, but I don't actually despise vtubers with every fibre of my being. I just find them sort of annoying, and I enjoy being melodramatic about mundane things. But even if I did, even if the only reason I bothered to make this topic at all was because I froth at the mouth thinking about those accursed deadbeats and karakoe nights with the shark, it wouldn't matter even a tiny little bit. It doesn't matter who makes the BUR, as long as it's a good BUR.
Now, let's address the examples you bring up of snake hair ornament and frog hair ornament (and the accusations of me ignoring them on purpose). I was recently made aware of monocle hair ornament in the Discord server and, seeing the writing on the wall, asked if there were any other similar accessory tags that applied to literally just one character. What you see in the above BUR are all such tags that were brought to my attention at the time. I was certain there'd be more, which is why I asked in the BUR that includes more than one non-vtuber accessory for other users to please list any they were aware of.
I know this isn't going to do me any favors in regards to the vtuber bias you believe me to be under the spell of, but I actually don't have a problem with snake hair ornament and frog hair ornament. The three most common kinds of hair ornaments seems to be simple shapes, animals and food - meanwhile, as far as snakes and frogs go, they fall into the "preschool animal" category, being commonly used to teach children the alphabet. Being the incredibly basic and widely known animals that they are, it's no surprise that we already have hundreds of hair ornament posts for both of them that have nothing at all to do with Touhou. Again, my issue with these hyper-specific accessory tags isn't when one character dominates the results for them. If you can exclude that outlier from the search and find many valid results, then the tag is more than fine. However, when the entire tag consists ONLY of said outlier, then it doesn't actually do anything at all.
