It is true that you do not necessarily get all the correct information from these sites. I was very interested in someone who had added us to his family tree, and so looked into his, only to find that I was a lot younger than I am and my husband was my father! I of course told him of this, and gave him as much information as I could to put him right, but I am not sure how far back he was going to have to go to get to the bottom of his mistake. Unfortunately I have given up on this project for the time being, I seemed at one time to be going round in circles, and I do think that it is a good idea just to sit back occasionally and have break.
