This study in no way outs men impersonating women. In fact it specifically identifies gender for analysis by comparing it to the linked blog/website profile information and assuming that "the effort involved in maintaining this deception in two different places suggests that the blog labels on Twitter data are largely reliable". Basically it assumes that anyone attempting to impersonate the opposing gender is a tech ignorant moron that has made no effort to create a persona - something that is contrary to pretty much every piece of information we have on people who do this.
Overall, a poorly constructed study that oversells what it discovers and is then exagerated and stretched by the media who claim things that even the study isn't pretending that it does - in other words a typical day in research and scientific reporting.
