If you think someone on Derpibooru is faking a death for money or attention, that is a very serious matter. I would recommend reporting them (either their profile or a comment/image where they make that claim) with sufficient evidence for us to evaluate that, and we’ll go from there.
As for posting about it - I can’t exactly endorse that because of the drama and controversy that would likely ensure, but I won’t stop you either. All I can say on that matter is that you better have damn good, verifiable, and convincing evidence to make such a claim, as death is a very touchy subject, and if you make a claim that turns out to be incorrect, that will really upset some people.
Also if it’s just text, a forum post would probably be better than an image.

Let’s not make public assumptions without evidence, please. It could be coincidental timing, or perhaps you could be right, but I’d rather not go from “someone may be exaggerating their death” to “Oh! Is it <name>?”. This isn’t a guessing game where anybody wins.
Again, touchy subject.
