Well I am shocked by this. byuu's contributions to the emulation community are so much I cannot even recount. A great, great loss.
I mean, most of us had never heard of this KF before, so should they have desired to troll byuu, those who know and collaborate would likely never know. However, tactics by the scum who troll together come in many, many forms, that are usually not openly broadcast on the internet. They harass people online yes, but also privately though electronically by other means.
These groups do tend to harbor intense hatred for those identifying LGBTQ+. Online trolling one's sexual/gender identity seems to be their favorite sport. byuu by own admission had significant psychological struggles, and was autistic. That is like the trifecta to these deviants. What byuu's online participation was totally irrelevant, they made the perfect mark by being an online personality of some type and again, having the traits the trolls wish to harass over.
