reviews and prevent to take ownership of comments

[Markoh75]

Every now and then some reviewers takes ownership of  my comments. I am the initiator of the document and I do not want this top happen. When I ask the users how they did it nobody knows.
So what makes this possible? How do i prevent this from happening.
Now every comment I have made is something like this "on behalf of xxx".
So suddenly all my comments are gone and can be found under other reviewers name.

You can lock them, but that's about it, and it doesn't make them un-editable, only makes it more difficult to do so.

Thank you for replying.
I wonder why this occurs now, we have been using Acrobat for years and last weeks this have occured.
I have never seen that someone can take ownership of my comments. The locking is not so optimal, I have to do this separately for all comments. If I lock it then I cannot edit them either...

It's a persistent, time-wasting problem, and alas, so far I haven't heard of a solution...
