Has anyone else had any trouble with Ancestry.com being inaccurate?

Question:

Has anyone else had any trouble with Ancestry.com being inaccurate?

I tried to update Ancestry.com with my family tree information and I noticed that someone corrected it and made my grandfather and cousin linked to someone else's tree and I know for a fact that it isn't so the way they fixed it. How do you prevent this from happening? I thought it was for people to update their own personal tree not someone else's.

I think the most horrible violation of my family tree was when they changed around the people whom I am still in contact with as if they knew them or something!
