Re LDS and ancestry.com [View all]

I have been a long-time member of ancestry.com.
I have entered much information regarding my ancestors and family, including my deceased brother and sister.
Just the other day I saw (on the connectivity section) that someone whom I had never communicated with before had copied my info on several close relatives.
As is my wont, I sent a note through ancestry.com inquiring of the relationship connection. I am very willing to share info, and have learned much of more distant relatives and ancestors through this communication.
I have had no response to my note as yet.
I tried to find a connection online, but could not discern any connection.
Tonight, I tried to trace the name of the member who had used my family's data through ancestry.com's search mechanism, and found out that the person (or someone with the same uncommon names) lives in Salt Lake City, Utah.
Then it struck me that perhaps my family members were copied to be used in the LDS practice of baptizing nonmembers after death.
I have nothing against LDS or its members, but would not want my family used in this manner.

What do DU members think is the possibility that this is the case?
Am I being paranoid?
It is not my intention to offend anyone who reads this.
