I don't think anyone was just adding profiles willynilly. The person who originally put up the profile also put up and number of Hauenstein profiles, and Vaudis married a Hauenstein, so there is probably a connection that just hasn't been made. The person who adopted the profile also adopted many orphaned Hauenstein profiles, Again, no problem.
There is also no problem with posting a profile for a person, whether you are related or not. If it were wrong, most One Name Studies would be out of luck, and most people would not be able to post EurAristo profiles, Cymru profiles, Scottish Clans profiles, etc..
There are potentially two problems:
1. Someone thinks the picture attached to the profile is a photo of grandmother. This is indeed a mystery. Maybe they just look alike. More info is needed from Anonymous.
2. The profile contains a verbatim obituary..This may or may not be a problem. If the person who originally posted the profile wrote the obituary and paid to have it published or had the permission of the person who did write and pay for it, OK. (Should have cited the origin) If the person just lifted the obit, without any cite, that is wrong and should be corrected.
