Findagrave has recently (2014) been bought out by ancestry.com. There will be more for-profit changes to come.
The intent of the site was to document every grave in the world for public consumption. The ethics of that quest are much debated, no respect for the dead or their living family is given. Often the crass and tasteless will post private medical information such as death certificates on these supposed "memorials". How can anyone consider a death certificate as a memorial item?
The heartless site owners state clearly they have no respect or regard for any privacy of dead people. It's a fact in their guidelines. A very few people, the shameful and disrespectful few, take great pride in their hobby of owning information of dead strangers. They are by far outnumbered by the family-connected members who attempt to honor both the dead and the surviving family.
Until this for-profit site is forced to stop allowing a few numbers-hoarders to cease their disrespectfull behavior the site will continue to be riddled with bad behavior. Again, it's only a few who control massive numbers and those few need to be stopped.
The advice to delete memorials you manage does not work! All that does is leave an empty slot for the shameful numbers-whores and they'll go fill it as fast as possible so they can OWN the memorial for YOUR dead relative.
Findagrave guidelines require the newer creator to delete their site if an older one exists. If you want privacy for your deceased relative, quickly create the memorial page, list the bare facts and in the profile explain that this is a placeholder that the family owns and is there to protect the privacy of the deceased and the surviving family.
