Meh, it’s a Japanese thing, and therefore Japanophiles enjoy using that iconic imagry around the world. Japan only more recently started leaving behind their extremely heavy prudishness, similar to the 1960s hippy movement in most Western nations, and so this is their version of a “scantily-clad female”, dressed up specifically with the intent of causing excitement. I doubt many people ever physically wore such an outfit, although the way it looks here makes it look more like something you’d see in a Vegas-style casino (irl image, mostly SFW but still out of sensitivity I am merely linking rather than auto-displaying it here), which is an exact analogy to the more anime & video-game style.

Also btw there is a male version - e.g. the chip & dale style. Example irl image. Notice how both the above for woman and this here uses fishnets, either as tights or in lieu of a shirt.

The point though is that they are “dressed to impress”, and like not in a business suit kinda way, but rather to titillate and excite the audience, even if just shy of the NSFW line. Joss Whedon’s (and so many others) “lens flares” in movies or is a non-person example - something that adds little to nothing in the way of substance, and in fact somewhat even if only slightly distracts from such - and instead is purely for style. Another example would be those wing / wind-spoilery things on cars, which if you are doing city driving you will literally never get any functional benefit from whatsoever, yet they help them sell b/c it pushes an “image” to the potential purchaser.

TLDR: one way to think about it is that comforting lies are style over substance, while unpleasant truths are substance over style. Though really that’s kind of a distracting dimension, since no matter how you package the latter people don’t tend to enjoy it, and vice versa for the former… - but still, those thoughts do often travel together.

Because even if it’s low res it’s enough to clearly see that she has tits

Lemmy has an enormous down-vote problem, far worse even than Reddit somehow imho. Somehow the old chat forum way of “this response is relevant to the subject and adds to the conversation”, as yours did, is mostly ignored in favor of “I enjoy seeing this, so I am going to click the LIKE button”. (Implicitly, the hidden third option, of simply leaving it be, is likewise passed over, in favor of what I can only presume is due to lonely people desperately seeking to have some kind of interaction with the world.)

For me personally, I try go by the adage “don’t be a jerk”, but there are MANY people who apparently disagree with that:-D. One enormously crucial component of that is that the apparent anonymity of downvotes is an inherently unequal one - without being an administrator of an instance, I cannot easily find out who downvoted something, so they can make those kinds of hidden comments about me (or in this case you) that I can do nothing to block (short of moving to an instance that does not show downvotes of any kind whatsoever). This is why, whenever I do want to downvote someone, I always take the time to explain it in a comment, or upvote an existing explanation that does the same, so that the recipient is made aware of why people are saying that it is less relevant or should not exist. (major exception: unless it is an obvious troll - they already know, they simply don’t care, and those I most often don’t even bother to downvote, and rather simply block and move on with living my best life, free from that noise)

This downvoting issue has several problems, one being that different people like different things (e.g., gosh if you can believe it, even non-Linux operating systems, gasp!:-P), and how we NEED diversity of cultures (and ages, genders, walks of life, etc.), but yet downvoting creates echo chambers and discourages participation. I dare say that the top criticism of the Fediverse is the overall lack of content, and therefore the downvoting issue is the top reason why more people do not share content, and therefore our stupidity is the top reason why if it dies, this is what will be that killed it. i.e., if I am going to be spit upon, perhaps I will show up the place that did that less frequently? Other people can do whatever they choose… yet so too can I.

So my advice is: (1) read the cargo cult of the ennui engine, then (2) feel pity for all the people who can only accept precise clones of themselves and cannot enjoy or even simply leave alone someone else saying something that they do not 100% agree with, but feel compelled to respond, almost like it is themselves that they are arguing with inside their own heads rather than you.

TLDR: Karens are going to Karen, and until alternatives to Lemmy are developed (Sublinks and Piefed are both coming!!), there’s nothing anyone seems willing do about it.
