I've always written after my corrections, that if the author feels that I was too nitpicky, I will back off. I've always written them with the aim to be constructive rather than just badmouthing their work.
There are a few reasons why I am not an editor. If the work has too many mistakes, I find it hard to read through. I also don't have a lot of time on my hands. And I doubt I'm that good a editor, but if a particular writer approaches me, I will certainly give it a shot. Anyway, my grasp of the English language and its intricacies are often lacking when it comes to the subtleties that an editor has to/should catch.
May I ask which comments on which book made you write this message?
