The inclusion of the nosebleed is not to make fun of Matt, it is to highlight something relevant to the medical issues that people have speculated about. The motivation is to bring to light Matt's wide-ranging exploits in one place, given it is abnormal for someone involved in high-profile litigation to spend their time arguing on Hacker News, Reddit, Twitter and live streams.
People are signaling to you that this particular thing crosses a line. You'd do well to heed that and take that part out. Speculating on his health / insinuating things undermines the points you're trying to make.
Matt doesn't appear to have a problem with the website ("It actually is an excellent website"[1]). Please create a Pull Request with any changes you think necessary.
In the context of man off the rails, wrecking careers and reputations, etc. the nose bleed is a possible signal. It's not something to be ignored, again based on the context.
Frankly, it would explain a lot. Cause as it is, it's baffling.
