The LDS Genealogy center was created in order to baptize people posthumously. They do this to all people of any religion all over the world. The major Jewish organizations objected to them about this and they said they would stop. However they continued to do this as far as I know.
Years ago Rav Chaim Pincus Scheinberg said it was forbidden to have anything to do with them. Currently I don’t know if he still holds this view as things might have changed.
This organization spends hundred od millions of dollars to translate and glean information from birth, death and marriage records all over the world. The only reason that they continue to do this is for their religious reasons.
I am a Genealogist and know that these records would be helpful in my research but don’t use them because I have not found any Rav who would approve of this.
Today with the internet there are so many ways to get this information that they can be avoided completely
