Not by reverting it, reporting it for vandalism, thanking it, or commenting at it. As Jack Munzel’s answer says, it’s a bot, and it’s a very stubborn bot at that.

Christopher VanLang has indicated the only way to stop QCR edit warring you is to report its action as a bug. That, at least, will actually get looked at by a human. I can report that it’s stopped a couple of my edit wars with QCR.
