I agree that all info should be added by hand and not merged with a single click. In the case of my tree that I have worked meticulously on for the past 3 years a name collector grabbed a huge chunk of the tree and added it to hers even though she was just distantly related through marriage. I was mildly irritated but the info was correct and she did give me credit for the photos. The next person to do this I could not see how he was related to me at all. This person merged a large portion of my tree into theirs but somehow shaved the first names off - Mary
Christie instead of Gertrude Mary
Christie - Thompson
Taylor instead of George
Thompson Taylor. You get the picture. What a mess! It does look like it was the work of the merging software. I quickly made my tree private but alas too late I think.
