I assume you're talking about near (fka byuu)? Heartbreaking...such an unbelievably intelligent and insightful person.

I had the pleasure of getting a couple direct replies from them once on an obscure subreddit under my own realname account. That turned into a few DMs, and despite the fact that I was publicly working on tech completely antithetical to their technical views, they were so gracious and thoughtful and engaged...it was truly humbling.

I have my own thoughts on KF too...I wish the individuals responsible for their targeted and direct harassment had been held accountable. But I'll try to preserve some tact in their memory and leave it at that.
