When I see an obituary about someone of whom I know little, I always plug military service.
It is what one does not say that is important. To be sure, causes of death may indicate things derogatory... but I dislike the term "pass away" for violent death (including vehicle crashes, industrial accidents, military deaths, falls, and fires. I try to avoid mentioning STD's and death from suicide (unless more than 80 years ago or connected with ill health or "despondency"). I do not want loved ones to feel guilt.
I have no connection to people who died in the Holocaust, but I would not call being gassed, hanged, or shot by the Nazis -- or of overwork under starvation rations -- as "passing away". (So much for a peeve).
I do not protect the identity of the dead. If someone sees what I have as largely citations of the census, marriages, death records, birth records, and military records... then I invite others to add details As I live in a rural area and factory town, I find it hard to make people interesting if they were farmers or factory workers.
...It is up to others, as I am a documents person more than a story-teller, in genealogy. If you know that someone graduated from college (date and degree), then put that in! If you have a photo, then show it! Running for and winning elective office? Show it! This is a collaborative effort, and anything done in reason (please -- avoid derogatory rumors! I will remove potentially-libelous material if it does not have documentation behind it).
So be careful about affairs, criminal records, bankruptcies, and the like.
