>>50066329Do you want the unironic answer?
Because of two groups. The vtuber antis who turn every possible connection between a male and a female into an opportunity to dunk on gachikois, and the normalfags who call gachikois incels when they push back against vtuber antis and also do the same if one of their ilk(usually the anti-unicorn type) brings said male interaction to normalfags attention via clips or tweets or whatever
It makes every single male interaction a chip in your reputation, which ends up being anathema to gaining additional gachikoi viewers because they'll have heard of you and [man here] that you [did thing to/at/with here]
Look at fallenshadow for example, she should be damn near messiah tier for gachikoi, but instead gachikoi and unicorns who don't know her think "oh she's a liar and has a boyfriend or something, right?"
The thing is that gachikoi aren't going anywhere, they're a significant and stable demographic of the vtubing mainstream. They're very lucrative and oftentimes completely harmless outside of their specific type of yab(won't bitch about the usual things fans bitch about i.e. game choice, skill, politically incorrect language, etc etc), so if a vtuber is okay with that type of fan, they usually try pretty hard to at least grab their attention because everyone knows they exist
So any hint of male interaction risks doing damage to your "gachikoi credibility", which ends up damaging your prospects as a vtuber
You would have to get rid of the people who want to scare away gachikoi(either to hurt the vtuber, or out of their normalfag moral outrage) to make harmless interactions actually harmless
And good luck with that kek
