I've encountered that before as well. I was kind of wondering if it might be a good idea to have "last updated by" on each page. The two main reasons for that would be because if you sign your name to something, you might try to be a bit more sure, and if cases where here's some discussion, you can actually track the person who "probably" changed your edit and you can ask why. They either have a good reason that perhaps you didn't know, or it's educational for them and they think twice next time. I highly doubt anyone is making changes just out of spite, but ignorance can only be corrected through education.
In my experience this is a bit more art than science and some of the information is both debatable and open to interpretation.
